D Correct answer
Explanation

Volume of a circular prism (cylinder) = pi * r^2 * h. Volume = 3.14 * (2.9)^2 * 6.8 = 3.14 * 8.41 * 6.8 = 179.57072.

AI explanation

A circular prism is geometrically a cylinder, and its volume is calculated using the formula pi times r squared times height. Substituting the given values, the volume is 3.14 times 2.9 squared times 6.8. This calculates to 3.14 times 8.41 times 6.8, which equals 179.56672 cubic metres.
