What is the radius of a circle of 8 inches?
Since the diameter is 8 inches, then we can do 82 to find the radius, or 4 inches. The radius of the circle is 4 inches.
What is diameter of 8 inch circle?

How do you find the radius of a circle with inches?
How To Find The Radius Of A Circle
- The radius to circumference formula is: C = 2πr.
- The formula for radius to area is: A = πr2.
- If you need to go from radius to diameter, multiply radius times 2 : d = 2r.

What is the area of a circle with radius 8 inches?
Result in other units of area: A circle of radius = 8 or diameter = 16 or circumference = 50.27 inches has an area of: 1.29742 × 10 -7 square kilometers (km²) 0.129742 square meters (m²)
How to calculate the diameter of a circle?
The diameter of a circle is the length of the line starting from one point on a circle to another point and passing through the center of the circle. It is equal to twice the radius of the circle. It is usually denoted by ‘d’ or ‘D’. Diameter = 2 x Radius
Which is the correct formula for the radius of a circle?
Radius of a circle = Diameter/2. Or. Diameter of a circle = 2 x Radius. Let us discuss a few important theorems and their proofs related to the chord of a circle.
Which is the largest chord in a circle?
A chord passing through the center of a circle is known as the diameter of the circle and it is the largest chord of the circle. This diameter is twice that of the radius of a circle i.e. D=2r, where ‘D’ is the diameter and ‘r’ is the radius. Let us discuss a few important theorems and their proofs related to the chord of a circle.
