What is the formula to find the area of a circle with with a diameter?

if you are given a diameter divide it by two to get the radius! From then on, it is just simple Pi R Squared

The circumference of a circle is 132cm what is the radius of the circle in centimeters?

To find the radius of a circle when given the circumference, you can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 132 cm, you can plug this value into the formula: 132 = 2πr. To solve for the radius, divide both sides by 2π: r = 132 / (2π) ≈ 21 cm. Therefore, the radius of the circle is approximately 21 centimeters.

What is the radius of a circle with a circumference 26 inches?

To find the radius of a circle with a given circumference, you can use the formula: circumference = 2 * π * radius. Given that the circumference is 26 inches, you can plug this value into the formula and solve for the radius. Dividing the circumference by 2π gives you the radius of the circle, which in this case is approximately 4.14 inches.
