Question

What is the surface area of the cylinder? Express the answer in terms of -

d = 8 cm
h = 18 cm
Recall the formula SA - 23+ + 2
152
cm

Answer 1

Surface area is 176π cm²

Explanation:

Data

• diameter, d = 8 cm

• height, h = 18 cm

Surface area (SA) of the cylinder is computed as follows:

SA = π*d*h + π*d²/2

Replacing with data:

SA = π*8*18 + π*8²/2

SA = 144π + 32π

SA = 176π cm² ≈ 552.92cm²
