What is the approximate volume of a cylinder with a diameter of 12 meters and a height of 7 meters? Use 3.14 for pi.

A131.9 m3
B263.8 m3
C791.3 m3
D3165.12 m3

Verified Answer :

\(V=\pi r^2 h\)
r - radius, h - height
The diameter is twice the radius.

\(d=12 \ m \\ r=\frac{12}{2} \ m = 6 \ m \\ h=7 \ m \\ \\ V=\pi \times 6^2 \times 7=\pi \times 36 \times 7=252 \pi \approx 252 \times 3.14=791.28 \approx 791.3\)

The answer is c. 791.3 m³.
