Question

A cylinder has a radius of 16 m and a height of 9 m. What is the approximate surface area of the cylinder? Use 3.14 for π. A. 603 m2 B. 904 m2 C. 2512 m2 D. 14,469 m2

ANSWER IF YOU KNOW THE ANSWER!!!!!!!!!!!!!!!!!!!!
IF THE ANSWER IS WRONG I WILL REPORT YOU!!!!!!!!!!!!!

Answer 1

The answer is D. 2,512 m^2

Given: π = 3.14; r = 16 m; h = 9 m
A = 2πrh + 2πr^2; Where π = pi; r = radius; h = height
A = 2(3.14)(16)(9) + 2(3.14)(16)^2
= 2(452.16) + 2(803.84)
= 904.32 + 1,607.68
= 2,512 m^2
