The circumference of a circle that has a diameter of 8 inches is 25.12 inches.
What is the area of a 8 inch diameter?
64π square inches
A=πr2,where,r=8 inches given. So, A=π(8)2=64π square inches. i.
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.
What is the circumference of an 8 inch cake?
The circumference of an 8 inch cake would be 25.133 inches.
What is 8cm in diameter?
Circle with diameter 8cm. Circumference = π × 8cm = 25.1cm to 1 decimal place. Circle with diameter 16.5cm.
What is the radius if the diameter is 8ft?
Assuming that the “outside diameter” is the diameter of the circle, it is 8 feet, then the radius is 4 feet.
What is the area of a 8ft circle?
π = 3.14; r = 8 ft. A = 3.14 x 8 ft. x 8 ft. = 200.96 sq.
What is the length of a 8 circle?

How do you find the circumference of a circle with a radius of 8?
Suppose you only know the diameter? If the diameter is 8 cm, then the circumference is c = π(8) = 8π or 25.1 cm, rounded to the nearest tenth. A great thing about the formulas is that you can manipulate it to solve for an unknown if you know one of the other quantities.
What is the radius and diameter of the circle?
The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center.
How do we find the radius of a circle?
How to Find the Radius of a Circle?
- When the diameter is known, the formula is Radius = Diameter/ 2.
- When the circumference is known, the formula is Radius = Circumference/2π.
- When the area is known, the formula for the radius is Radius = ⎷(Area of the circle/π).
Can I Find area from diameter?
Answers. 1. The formula for the area A as a function of the diameter d of a circle is given by A = π (d/2)^2.
Is the diameter half of a circle?
Answer: Half of a diameter of a circle is called the radius.
How do I figure out 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 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.
What is the diameter of a cake?
12-inch diameter: 40 servings. A round cake pan is the pan that you’d use to make a classic layer cake or round birthday cake. The most common sizes 8 or 9 inches, but they come in a huge variety of sizes, which can be used to make cakes of varying tiers or size.
What is the circumference of a 10 inch diameter circle?
31.42cm
Answer. We know that C = πd. Since the diameter is 10cm, we know that C = π x 10cm = 31.42cm (to 2 decimal places).
