The diameter of a sphere formula with volume is, d = (6V/π)^(1/3), where d is the diameter of the sphere and V is its volume. Alternatively, we can substitute the value of V, in the volume formula, V = (4/3) π r3, solve it for r, and make it double to find the diameter.
How do you find radius with only volume?
Answer: To find the radius of a sphere with the volume, we use the formula: r = (3V/4π)
What is the formula for finding the diameter of a circle?
Radius is the length of the line segment from the center of the circle to an endpoint on the circle and diameter is twice the length of the radius of the circle. Using this definition, the formula for the diameter is D = Radius × 2.
What is a circle diameter?
Diameter of a circle
The diameter is the length of the line through the center that touches two points on the edge of the circle.
How do you find the radius of a circle with the volume and height?
They were all derived directly from the above equations.
- Given height and volume: r = √(V / (π * h)) ,
- Given height and lateral area: r = A_l / (2 * π * h) ,
- Given height and total area: r = (√(h² + 2 * A / π) – h) / 2 ,
- Given height and diagonal: r = √(h² + d²) / 2 ,
How do you find the diameter of a cylinder with the circumference?
If you want to find the diameter from the circumference of a circle, follow these steps:
- Divide the circumference by π, or 3.14 for an estimation.
- And that’s it; you have the circle’s diameter.
How do you find the diameter of a tank?
EASY WAY – Take a piece of string, and wrap around the tank. Then cut or mark the string so you can measure the total Length. Divide that number by 3.14 to get your Diameter in Inches. The number will always be higher, since you are measuring the outside of the tank.
What is the diameter of a cylinder called?
The diameter of the piston, and the inside diameter of the cylinder, is called the bore – B. So the area A of the head of the piston is pi (3.14159) times the diameter squared divided by four.
How do you find the diameter and radius of a circle?
Take the circumference of a circle and divide it by Pi. For example, if the circumference is 12.56, you would divide 12.56 by 3.14159 to get 4, which is the diameter of the circle. Use the diameter to find the radius by dividing the diameter by 2. For example, if the diameter is 4, the radius would be 2.
What is radius and diameter of circle?
While the radius of a circle runs from its center to its edge, the diameter runs from edge to edge and cuts through the center. A circle’s diameter essentially splits the shape in half.
How do you find the diameter of a circle without the radius?
If you don’t have the radius, divide the circumference of the circle by π to get the diameter. If you don’t have the radius or the circumference, divide the area of the circle by π and then find that number’s square root to get the radius. Then, you can just multiply the radius by 2 to find the circle’s diameter.
How do you find the radius with the diameter?
Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet.
How do you find the radius of a cylinder if you know the diameter?
The radius of a cylinder(r) = √(V / π × h), where V is the volume of a cylinder, h is the height of the cylinder, and π(Pi) is a mathematical constant with an approximate value of 3.14.
How do you find the diameter of a circle with a ruler?
Measure just the radius of the circle if it is very large. The radius is the distance from the center to any point on the circle. Multiply the radius by two to produce a measurement for the diameter.
How do you solve for diameter?
The formula to find the diameter states the relationship between the diameter and the radius. The diameter is made up of two segments that are each a radius. Therefore, the formula is: Diameter = 2 * the measurement of the radius. You can abbreviate this formula as d=2r.
How do you measure the diameter of a propane tank?
Propane Tank Sizes
- Step 1: Set your propane tank on its bottom, and measure the height from the bottom to the base of the tank’s collar, the raised piece of metal that surrounds the tank’s valve.
- Step 2: Measure the diameter of your propane tank by encircling it with your measuring tape at its widest point.
How do you calculate volume of a tank?
The formula of volume of the rectangular tank is given as, V = l × b × h where “l” is the length of the base, “b” is the breadth of the base, “h” is the height of the tank and “V” is the volume of the rectangular tank.
How do you calculate volume?
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
What is the diameter of a solid right circular cylinder?
Hence the diameter (in cm) of a solid right circular cylinder is 2.4.
What is the volume of cylinder?
The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h .
Is diameter half a circle?
The center of a circle is the midpoint of its diameter. That is, it divides it into two equal parts, each of which is a radius of the circle. The radius is half the diameter.
