What is the area of the circle of radius 7cm ?
49cm2
22cm2
154cm2
308cm2
Area of a circle = pi * r^2. With r = 7, Area = (22/7) * 7 * 7 = 154 cm^2.
Using the area formula for a circle, Area = pi * r^2. Substituting the radius of 7 centimeters and pi as 22/7 gives (22/7) * 7 * 7. The result is 154 square centimeters.
