I believe the answer is B: 3 + 7 + (-10).
1908
Step-by-step explanation:2% of 1800 is 36 36 x 3 is 108 + 1800 =1908
R = sqrt 3 * (V /( pi * h))
V = 62.8
pi = 3.14
h = 15
now we sub
R = sqrt 3 * (62.8 / (3.14 * 15)
R = sqrt 3 * (62.6 / 47.1)
R = sqrt 3 * 1.33
R = sqrt 3.99
R = 1.9 rounds to 2 inches <===
360 degrees in a circle divided by 5 is 72
