56.52 ÷ pi(3.14) = 18
18 ÷ 2 =9
A = pi(3.14)r^2
A = 3.14 × 9^2
A = 3.14 × 81
A = 254.34in^2

Answer:
131 degrees
Step-by-step explanation:
When you take all parts of the circle and add them up, you are given 31y-12.
When you set 31y-12 to 360 (31y-12=360), you can solve for y and plug it in to all variables of the circle.
31y-12=360
Add 12 to both sides to cancel it out from the left.
31y=372
Divide 31 on both sides to cancel out and leave y on the left.
y=372/31
y=12
Now, plug 12 in to each variable. 54+77=131 degrees
