C=2πr
75=2 (3.14) (r)
75 = (6.28) (r)
r= 11.942675
rounded to the nearest foot is 12.

Answer:
A. 13.5
Step-by-step explanation:
60 ft. = 3 in.
20 ft. = 1 in.
270/20 = 13.5
The number that is missing is 83
N-6/n²+11n+24/n+1/n+3
First, we need to factor the following:
n² + 11n + 24 → (n + 3)(n + 8)
n² → n * n
factor of 24 are:
1 x 24
2 x 12
3 x 8 We will use these factors. 3 + 8 = 11
4 x 6
Division involving fractions results to multiplying the first fraction to the reciprocal of the second fraction.
n-6/(n+3)(n+8) * n+3 / n+1 → n+3 is in both numerator and denominator. Cancel each other out.
n-6/n+8 * 1/n+1
n-6/(n+8)(n+1) Correct answer is Choice D.
