Answer:
A = 1/2(2πr)(r)
Explanation:
The circumference of the circle, 2πr, is the measure completely around the circle. When the pieces of the circle are rearranged, half of this circumference will be on the top of the parallelogram and half will be on the bottom. This means the base will be 1/2(2πr).
The approximate height of the parallelogram is the radius of the circle; this makes the area
A = 1/2(2πr)(r)
Well idk what the numbers are, but the formula to find the are is 3.14(pi) x r^2
180 is the degree of the whole angle so you subtract 180 from 77 to get P
180-77=103
P=103
