At the rate of $2.00 per square foot, the cost of painting the rectangular board with a semicircular top shown in the figure is $? Assuming pi = 3.14
I 've been stuck on this for so long can someone please help me out?!
3x4 =12 (this is the square) 1.5 x 1.5 x 3.14= 7.065 however since it is a half of circle we divide 7.065 by 2 = 3.5325 Now add 3.5325 and 12 = 15.5325 round it to 15.53 then multiply by $2 The answer is $31.06
