Answer:
9.82 inches²
Step-by-step explanation:
both areas are equally sized, so they are both half of the whole circle.
circle area : pi × r²
half of the circle area is therefore pi × r² / 2
the picture gives us the diameter of the circle, the radius is half of the diameter.
=> r = 5/2 = 2.5
=> shaded area = pi × r² / 2 = pi × (2.5)² / 2 = 9.82 inches²
Answer:
x = 47 degrees
Step-by-step explanation:
First, find the supplementary angle by subtracting 180 from 103, which you get 77 degrees.
Then, add 77 and 56 to get 133 degrees.
Subtract 180 from 133 and you get 47 degrees.
Answer:
−40+2n=−4n+8
−40+2n+40=−4n+8+40
2n=−4n+48
2n+4n=−4n+48+4n
6n=48
answer: n=8
