Question

The height of a cylinder is 16.5 centimeters and the volume is 4,196.61 cm3. What is the radius?

Answer 1

ok, the equation for the volume is v=
`\pi`r^2h

so 4,196.61= 3.1416r^2(16.5)
4,196.61= 51.8364 r^2
51.8364 r^2 = 4,196.61
r^2= 4,196.61/ 51.8364
r^2= 80.95
r= 8.99

your radius is 8.99
