Area of a circle = (3.14) * r^2 radius = diameter/2 radius = 4/2 r = 2
A = (3.14) * 2^2 A = (3.14) * 4 A = 12.57 since it's a half circle though, 12.57/2 = 6.29
the area of the rectangle is bh, 4*2 = 8
6.29 + 8 = 14.28 area = 14.28
perimeter of a circle, or circumference = 2(3.14)r C = 2(3.14) * 2 C = 6.28 * 2 C = 12.57 but again, since it's a half circle, 12.57/2 = 6.29
perimeter of a rectangle = 2(l + w) p = 2(4 + 2) p = 2(6) p = 12 but because the perimeter is what's on the outside, we don't count the side connecting to the circle, so it'd be 12 - 4 = 8
