find the volume of cone whose height is 5 cm and its radius is 3 cm.

Question

Surface areas and volumes

Answer 1

For volume, use the equation:

where π ≈ 3.14, r = 3 and h = 5

For surface area, A = Area_bottom + A_side = πr² + πrl where "l" is the slant height. Since you don't have the slant height. use the Pythagorean Theorem to get it. l = √(r² + h²) so:

SA = πr² + πr√(r² + h²) and use the same values for "r" and "h" and π
