Question

Find the volume and the surface area of a cylinder where r:
= 8m, h = 15m

Answer 1

volume = 960π m³ ; surface area = 368π m²

Explanation:

base area = 8²π = 64π m²

base perimeter = 8 x 2 x π = 16π m

lateral area = 16π x 15 = 240π m²

surface area = 2 x 64π + 240π = 128π + 240π = 368π m²

Volume = 64π x 15 = 960π m³
