Answer:
D) 191
Step-by-step explanation:
The entire circle is 254.5, calculated by using this formula

Only 3/4 of the circle is needed for the area, however, so you multiply your area by 0.75

and

(f+g)(x) =

combining like terms gives you answer choice B
11/21 written as a decimal would be 0.52381 and in percent, it would be 52.381%.
To solve percent, since the total or 1/1 is 100%, we have to remember that the answer is less than 100%. So, we move 2 decimal places right to make it into percent. Then, the answer is 52.381.
To solve percent, you would do 100/21. Then, you would get 4.7619047619. You multiply that by 11 and get 52.381. But, you have to move 2 places left since fractions are tens, hundreds. So, you would get 0.52381.
