Answer 1

Answer:

37.68ft³

Step-by-step explanation:

So the formula for the volume of a cylinder is base x height our height is 3 but we have to find the area of the base:

the formula is: radius² x 3.14 (pi)

so we find the radius by dividing the diameter by 2: 8 ÷ 2 = 4

4 x 3.14 = 12.56

So the area of the base is 12.56ft²

now we plug that into our equation:

12.56 x 3 = 37.68

So the volume of the cylinder is 37.68ft³

hope this helps:)

Answer 2

Answer:

150.80 sq ft

Step-by-step explanation:

Area of a cylinder = area of circle x length

r = 8/2 = 4

$4^{2}$π x 3 = 48π = 150.7964474
