four semicircles is really 2 full circles
So the area would be the square plus 2 circles.
Area = 36 + pi(3)^2
= 64.26 or 64 cm^2 to the nearest whole number
The circumference would simply be the sum of the arcs of the four semicircles or the circumference of two circles
C = 2(2pi(3)) = 37.68 cm or 38 cm rounded to nearest whole number
Can I get help with some problem that its asking saying, "An inscribed regular triangle is removed from a circle with a circumference of 36 pie. Find the remaining area.
