Question

Find the surface area of the cylinder in terms of pi.

Answer 1

104π cm²

Explanation:

Surface Area of cylinder

• SA = 2πrh + 2πr²
• SA = 2πr (h + r)
• r is the radius and h is the height

Given (from the figure)

• r = 4 cm
• h = 9 cm

Solving

• SA = 2πr (h + r)
• SA = 2π × 4 (9 + 4)
• SA = 8π × 13
• SA = 104π cm²
