radius is 5cm. pi x r2 is 78.54, /3, *2 is 52.36cm2
1.27 units 8/pi = 2.5464 2.5464 / 2 (you divide by two because the 2.5464 is the diameter of the circle. two radius = one diameter) = 1.273 round. 1.27
Round 502.6507568359375 to the nearest hundredth is 502.65.

If you have the radius, then area = pi*r2 which you then round to the nearest hundredth. If you do not know the radius but do know the diameter or circumference, you can calculate the radius. Otherwise you need to measure it.
A circle with a radius of 4 units has a circumference of 25.13 units.
The area of a circle is: pi times radius squared
201.06.

The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius. Given the radius as 47, the circumference would be C = 2 * 3.14 * 47 = 294.04. Rounding to the nearest hundredth, the circumference is approximately 294.04 units.
