PLEASE HELP!




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 please?

Answer 1

surface area = 346.2 ft
volume = 538.8 ft

Answer 2

the volume of a cylinder = area of the base ( circle) x heoght

now the area of the circular base = pi x r^2
where
r = radius
pi = 3.14 ( approximately)
= 3.14 x 3.5 x 3.15
= 38.465 sq.ft
now to find the volume we have to multiply that value by the height
volume = 38.465 x 14
= 538.51 cubic ft.
if we round off it to the nearest tenth we will get
volume = 538. 5 cubic ft.

now to find the surface area
Area = 2 x area of the circle + area of the curved part

area of the curved part = circumference of the circle x height
= 2 pi r x 14
= 2 x 3.14 x 3.5 x 14 sq. ft
= 307 . 72 sq. ft
now the total area = 307.72 + 38.465 sq ft
= 346 . 185

if we round off it we will get
346.2 square ft.

hope this will help ya :)
