This is a square in the center with 4 semicircles "glued" to the sides. Use Pi = 3.14 and ROUND your answers to the nearest WHOLE unit)

**Reiny**, Thursday, May 22, 2008 at 10:58pmfour 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
