Answer:
if 
is not divided by 
, then y - intercept becomes .
In such a situation, Shari thought that -192 was the y-intercept.
Step-by-step explanation:
Given: 
Solution:
Consider the equation:
To find y-intercept, put 
In the second step 
,
if is not divided by , then y - intercept becomes .
In such a situation, Shari thought that -192 was the y-intercept.
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.
