Question

Find the surface area of the cylinder. Type an exact answer in terms of pi.

Answer 1

154π cm²

Explanation:

Formula for the Surface Area of a Cylinder

• SA = 2πr (h + r)

Solving

• Here r = 7 cm and h = 4 cm
• SA = 2πr (h + r)
• SA = 2π × 7 (7 + 4)
• SA = 14π × 11
• SA = 154π cm²

Answer 2

154π cm²

Explanation:

Radius (r) = 7 cm

Height (h) = 4 cm

Surface area of cylinder

= 2πr (h + r)

= 2π (7) (4 + 7)

= 2π (7) (11)

= 2π (77)

= 154π cm²
