Question

The radius of a cylinder is 3.5 ft. The height is 14 ft. Find the surface area and volume of the cylinder to the nearest tenth of a foot. Show your work.

Need help asap

Answer 1

surface area:

A=2πrh+2πr2
=2·π·3.5·14+2·π·3.52
≈384.8451

volume:
V=πr2h
=π·3.52·14
≈538.78314

Answer 2

thank you @anonymous

Answer 3

I did 3.5 x 14 and then divided that answer by 3.14 and got 15.60509554140127. I don't know how to do this please help.

Answer 4

Volume = area of circle = pi r^2. Multiply by 14.

Circumference of circle = 2 pi r

Surface = 2(pi r^2) + (2 pi r)14
