Let's tackle the next problem. Problem 9: The radius of a circular roundabout is 7 m. Determine the area enclosed by this roundabout. Step 1: Identify the given radius and the formula for the area of a circle. The roundabout is circular. Given radius, r = 7 m. The formula for the area of a circle is A = r^2. We will use = (22)/(7). Step 2: Substitute the radius into the area formula. A = (22)/(7) × (7 m)^2 Step 3: Calculate the area. A = (22)/(7) × 7 m × 7 m A = 22 × (7)/(7) m × 7 m A = 22 × 1 m × 7 m A = 154 m^2 The area enclosed by the roundabout is 154 m^2.
