C is the correct answer

we should find the area of the square and then divide it by 24.
(360/15=24)

$6 \times 6 \times \pi \times \frac{1}{24} = 36 \times \pi \times \frac{1}{24} \\ = 113.04 \times \frac{1}{24} = 4.71$

good luck

Answer:
First choice is the correct one

Explanation:
The given is:
[(x+5) / (x+2)] - [(x+1) / x(x+2)]
First, we will need to have a common denominator and then we will solve the subtraction normally. To get a common denominator, we will have to multiply both numerator and denominator of first term by x.

Therefore:
[(x+5) / (x+2)] - [(x+1) / x(x+2)] = [x(x+5) / x(x+2)] - [(x+1) / x(x+2)]
= [x(x+5)-(x+1)] / [x(x+2)]
= (x^2 + 5x - x - 1) / [x(x+2)]
= [(x^2 + 4x - 1)] / [x(x+2)]

Hope this helps :)
