D Correct answer
Explanation

Radius = 150 cm = 1.5 m. Area = pi * r^2 = 3.14159 * (1.5)^2 = 3.14159 * 2.25 = 7.0685 m^2. Option D is the closest approximation.

AI explanation

First, convert the radius from centimeters to meters by dividing by 100, giving a radius of 1.5 m. Using the area of a circle formula, the area is pi * r^2 = 3.14 * (1.5)^2. Calculating this gives 3.14 * 2.25 = 7.065 m2.
