Answer:
The answer would be 27π
Step-by-step explanation:
the area is 36pi and the shaded region is 3/4 of the circle, as a 90 degree angle is 1/4 of a 360 degree circle. 3/4 of 36pi is 27pi
3/4 = .75 so you have to find 75 % of 3/9
100% = 3/9
1% = (3/9)/100
75% = (3/9)/100 * 75 =.25
The answer should be 9 rounded because 2 pi r 56.5 will give u that.
