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:
final for what?
Step-by-step explanation:
Step-by-step explanation:
(3x-2y)³=5³
(3x)³-3(3x)².2y+3.3x.(2y)²-(2y)³=125
27x³-54x²y+36y²x-8y³=125
Steps:
1. Do a proportion
X/799.45 times 15/100
2. Do 15 times 799.45 which equals 11,991.75
3. Divide 11,991.75 by 100
4. 119. 91 is the price being taken off
5. Do 799.45 minus 119.91
6. Your answer is
$679.54
