Question

Find the exact volume of the cylinder. A: 14pi m^3 B: 28pi m^3 C: 56pi m^3 D: 112pi m^3

Answer 1

Answer:

B: 28pi m^3

Step-by-step explanation:

r = 4/2 = 2 m

h = 7 m

Volume of cylinder

$= \pi {r}^{2} h \\ \\ = \pi \times {2}^{2} \times 7 \\ \\ = \pi \times 4 \times 7 \\ \\ = 28\pi \: {m}^{3}$
