Answer:
150.80 sq ft
Step-by-step explanation:
Area of a cylinder = area of circle x length
r = 8/2 = 4
[tex]4^{2}[/tex]π x 3 = 48π = 150.7964474
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:)
