A cylindrical cup is 8 centimeters in height. When filled to the very top, it holds 392饾潊 cubic centimeters of water. What is the radius of the cup, rounded to the nearest hundredth
The formula for the volume of a cylinder is: Volume = pi 路 radius2 路 height
Entering the known values: 392路pi = pi 路 radius2 路 height
Dividing both sides by pi: 392 = radius2 路 8
Dividing both sides by 8: 49 = radius2
Taking the square root of both sides: 7 = radius
Thank you Geno
