B, 190.
First you find the area of the circle (pi times radius squared) however, since you are given diameter, you must find radius by dividing diameter by 2. So, your radius is 9, then you plug it into the formula and you get 254.5. After multiplying this by 0.75 because you only want to find 75 percent of the area, you get the answer of 191m
Answer:
(x + 1)² = (2x)²
(1 + 1)² = (2(1))²
2² = 2²
4 = 4
(-1 + 1)² = (2(-13))²
(-12)² = (-26)²
Not true
x = -13 satisfies neither
A = 3,953 in²
You find the area of the whole triangle:
1/2bh = 1/2(63+31)(63+62) = 5875
Then subtract the missing rectangle:
lw = (62)(31) = 1922
5875 - 1922 = 3953 inches
Since you're multiplying inches by inches, it's inches².
