Question

9. A triangular prism and its dimensions are shown in the diagram. 13 mm 13 mm 14 mm 10 mm What is the lateral surface area of this triangular prism in square millimeters?

Answer 1

If there's a diameter of 14 feet, then the radius is 7 feet because it's half.

The volume would be

$V=\pi(r)^2h$

Where r = 7, so

$V=\pi(7)^2h$

Hence, the third option is the answer.
