Based in the given figure, we are being asked to solve the area and the perimeter of the semicircle. As we evaluate the problem, we can get a radius measurement from the rectangle. Hence, the radius is half of 4 inches which is 2 inches and since we know the formula for solving the area of a circle which is Area = pi*r², dividing the result by two, we able to get the area of the half of a circle which is equivalent to the area of the semicircle. Area of circle = pi*r² Area of circle = 3.14*(2)² = 12.56 Therefore, area of semicircle is = (1/2) 12.56 Area of semicircle = 6.28 inches²
Solving for the perimeter: Semicircle Perimeter = 1/2 * pi* d+d where d is the diameter (diameter = 4 inches) Semicircle Perimeter = 1/2 * 3.14*4+4 Semicircle Perimeter = 10.28 inches
