Answer:

Surface area = 207.24 in²

Step-by-step explanation:

Remember to always convert the diameter into a radius.

D = 6 in (divide it by two to get the radius) R = 3 in

Radius = 3 in

Formula:

SA = 2\pirh + 2\pir²

Solution:

SA = 2\pirh + 2\pir²

SA = 2(3.14)(3)(8) + 2(3.14)(3)

SA = 2(3.14)(3)(8) + 2(3.14)(9)

SA = 150.72 + 56.52

SA = 207.24 in²
