The area of a semicircle can be calculated using the formula:
Area = πr^2 / 2
Where r is the radius of the semicircle.
Given that the radius (r) is 7 cm, we can plug this value into the formula:
Area = π(7)^2 / 2
Area = 49π / 2
Area ≈ 77.94 cm^2
Therefore, the area of the semicircle with a radius of 7 cm is approximately 77.94 square centimeters.
