radius = square root of (531/pi) = 13 inches to the nearest integer
The surface area is 1,520.53 square inches.
The area of a circle is: pi times radius squared
if you mean a radius of 5 units then the answer is 78.54 APEX

To the nearest hundredth, the circumference of a circle with a radius of 4 is 25.13
The answer is 452.16.
The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
To calculate the surface area of a cylinder, you can use the formula ( SA = 2\pi r(h + r) ), where ( r ) is the radius and ( h ) is the height of the cylinder. If you provide the values for the radius and height, I can calculate the surface area for you. Otherwise, you can substitute the values into the formula to find the answer to the nearest hundredth.
A cylinder's length is 12 inches, and its radius is 6 inches. What is the surface area of the cylinder to the nearest tenth ?
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.
