The area is 81*pi-162. Look at the triangle formed by the chord and the two radii connected to the endpoints of the chord. Since 18^2+18^2=(18*\sqrt2)^2, this is an isosceles right triangle by Pythagorean theorem. The area of the quarter circle containing the region we look for is pi*18^2/4=81*pi. The area of the right triangle is 18*18/2=162. The difference between these two areas, or 81*pi-162, is the area of the smaller region.

Answer: 8 A.M.
Step-by-step explanation:
I dunno.
The answer should be D.
Hope it helped you.
Y=(x+7)/8
Work:
Y=8x-7 —> x=8y-7
Solve for y
x+7=8y
y=(x+7)/8
