The radius of the circle is 5inches what is the circumference?

The circumference of a circle that has a radius of 5 inches is 10 X pi or approximatly 31.415926535897932384626433832795. If you know the radius you can find the circumference by multiplying it by 2(pi)


If the circumference of the circle is 75.36 what is the radius?

To find the radius of a circle when given the circumference, you can use the formula: circumference = 2 * π * radius. Given that the circumference is 75.36, you can plug this value into the formula and solve for the radius. First, divide the circumference by 2π to find the radius. The radius of the circle would be 75.36 / (2 * 3.14159) ≈ 12. The radius of the circle is approximately 12 units.


How do you find out the circumference of a circle?

Circumference = 2*pi*radius or diameter*pi


What is the radius of a circle whose circumference is 94.2?

To find the radius of a circle when given the circumference, you can use the formula C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 94.2, you can plug this value into the formula: 94.2 = 2πr. To find the radius, you can rearrange the formula to solve for r: r = 94.2 / (2π) ≈ 15.0 units. Therefore, the radius of the circle is approximately 15.0 units.


How do you find cicumference with only knowing the radius?

To find the circumference of a circle you multiply pi, usually rounded to 3.12, by the radius. The formula for the circumference of a circle is 2*pi*radius. So double your radius, then multiply by pi, which is approximately 3.14159265 So if I had a circle of radius 2, my circumference would be 2*3.14*2 = 12.56 Good Luck!
