Question

The radius of a cylindrical construction pipe is 2 ft. If the pipe is 17 ft long, what is its volume?

Answer 1

Answer:

V = 106.76ft

Step-by-step explanation:

Cylinder Formulas in terms of r and h

• Calculate the volume of a cylinder: V = πr2h

• Calculate the lateral surface area of a cylinder (just the curved outside)**: L = 2πrh

• Calculate the top and bottom surface area of a cylinder (2 circles): T = B = πr2

• Total surface area of a closed cylinder is: A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

Answer 2

Answer:

$volume \: = \: \pi \times r {}^{2} \times length(height) \\ = 3.14 \times 2f \times 17ft \\ = 106.76ft {}^{3}$
