Question

Which equation can be used to find the surface area of the cylinder?

r= 6 cm

h = 8 cm

S= 28(8)2 +2 (12)(6)

O S=2(6)? +2(6)(8) *

O S=212)2 + 23412)(8)

S = 2846)2 +27(6)(8)

Answer 1

S = 2π(36) + 2π(6)(8)

S = 2(3.14)(36) + 2(3.14)(6)(8)

Explanation:

The surface area of a cylinder is the sum of the area of the base and the lateral area. A cylinder has 2 circular base .

Surface area = 2πr² + 2πrh

surface area = 2πr(r + h)

where

r = radius

h = height

surface area = 2πr(r + h)

r = 6 cm

h = 8 cm

The equation to find the surface area is represented below.

Surface area = 2πr² + 2πrh

S = 2π (6²) + 2π (6)(8)

S = 2π(36) + 2π (6)(8)

Assuming π is given as 3.14 the equation will be as follows

S = 2(3.14)(36) + 2(3.14)(6)(8)
