Question

What is the total surface area of the following cylinder?

A. 1,017.36 cm2
B. 791.28 cm2
C. 2,034.72 cm2
D. 395.64 cm2

Answer 1

2pi(r)(h)+2pi(r^2)
2pi(6)(15)+2pi6^2
565.4866776+226.1946711

B. 791.28cm^2

Answer 2

The correct answer is opyion B,

`791.28cm^2\\`

Explanation:

Surface area of cylinder

`= 2 \pi  r h + 2 \pi  r^2\\= 2 \pi  (6 cm)  (15 cm) + 2 \pi  (6 cm)^2\\= 565.48 + 226.19\\= 791.28 cm^2`
