Answer:
The exact answer is 27 * pi
or the approximate answer is 27 * 3.14 = 84.78
Step-by-step explanation:
First step is to find the area of the circle
A = pi * r^2
A = pi * 6^2
A = 36* pi
We are missing 90 degrees of the circle or 90 out of 360.
That means we keep 360 - 90 = 270 or 270/360
The fraction we are keeping simplifies to 3/4 (divide top and bottom by 90)
Multiply the area by the fraction that we kept.
36 pi * 3/4 = 27 * pi
The exact answer is 27 * pi
or the approximate answer is 27 * 3.14 = 84.78
