What is the exact volume of a cylinder that has a height of 1.8 ft and a radius of 6.1 ft?_____π ft³

Answers

Answer 1

Answer: cylinder area=height times area of base (area of base=area of circle)

height =1.8
radius=6.1
area of circle=pi times r^2

area of circle=pi times 6.1^2=37.21π
times height

1.8 times 37.21π=66.978π

volume=66.978π ft^3
