Question

Find the surface area of a Cylinder with a radius of 3.5 cm and a height of 6.2 cm

Answer 1

SA ≈ 213.31 cm²

Explanation:

Surface area formula or a cylinder:

SA = 2πr² + 2πrh.

Given r = 3.5 cm, and h = 6.2 cm.

SA = 2π(3.5)² + 2π(3.5)(6.2) →

SA = 2π(12.25) + 2π(21.7) →

SA = 24.5π + 43.4π →

SA = 67.9π →

SA ≈ 213.31 cm²
