Question

What is the surface area of the cylinder? Approximate using π = 3.14 and round to the nearest square meter.

a cylinder with a radius labeled 2.8 meters and height labeled 6.3 meters

99 square meters
122 square meters
160 square meters
553 square meters

Answer 1

The surface area of the cylinder is approximately 160 square meters.

The formula for finding the surface area of a cylinder is A = 2πr² + 2πrh. Plugging in the values given, we get:

A = 2(3.14)(2.8)² + 2(3.14)(2.8)(6.3)
A ≈ 160

Therefore, the surface area of the cylinder is approximately 160 square meters.

Answer 2

Equation:

SA= 2πrh+2πr2(squared)

SA= 2×3.14×2.8×6.3+ 2×3.14×2.8×2.8

SA≈ 110.8(LA) + 49.2

SA≈ 160.1m²
