Answer:
530.66 cm squared
Step-by-step explanation:
c = 2(3.14)r
81.64 = 2(3.14)r
Divide both sides by 6.28
The radius is 13
a = 3.14(13 squared)
a = 530.66
5' 4" = 64" (5x12)+4
2' 7" = 31" (2x12)+7
3' 10" = 46" (3x12)+10
64+31+46= 141"
141/12= 11.75= 11 3/4
12" per foot / 4 denominator from above= 3
3 numerator from above x 3 quotient from above= 9
11' 9"
For perimeter, just add all the sides together, if the side matches the side in front of it, make that side the same number. and then add. <span />
