I suppose the integral is
The integration region corresponds to a sector of a cirlce with radius 5 subtended by a central angle of π/4 rad. We can capture this region in polar coordinates by the set
Then , , and . So the integral becomes
-2,8 is the correct answer
Answer:
Step-by-step explanation:
To write the equation of a circle, use the formula where the center of the circle is (h, k).
This means the equation is .
Find the radius r by dividing the diameter of 10 in 2. The radius is 5.
So the equation of the circle is
Answer:
15.79%
Step-by-step explanation:
do 95-80 which is 15
then do 15/95 as a fraction then multiply that number by 100 to get 15 15/19 then turn that into a decimal and you get 15.79%
