The diameter of a circle begins at one point in the circle, passing through its center (midpoint) and ends on the other side of the circle. If we know the diameter D the length of the circumference is determined by: l=π⋅D. The area of a circle gives us ...
The total perimeter of the un-shaded part is made up of three sides of the rectangle and the perimeter of the half-circle. The area of a half circle = ½ π r2 8 π = ½ π r2; therefore r = 4 The perimeter of the half circle is ½ 8 π = 4 π The diameter of the ...
