Answer:
r = 8.12
Step-by-step explanation:
The volume for a cylinder is V=πr^2h therefore,
v = 2279.64
h = 11ft
r = ?
2279.64 = πr^2 * 11
![\frac{2279.64}{11}= {\pi r^2} \\](https://tex.z-dn.net/?f=%5Cfrac%7B2279.64%7D%7B11%7D%3D%20%7B%5Cpi%20r%5E2%7D%20%5C%5C)
207.24 = πr^2
![\frac{207.24}{\pi} =r^2\\\\66 = r^2\\\\\sqrt{66} = r\\\\\\8.12 = r](https://tex.z-dn.net/?f=%5Cfrac%7B207.24%7D%7B%5Cpi%7D%20%3Dr%5E2%5C%5C%5C%5C66%20%3D%20r%5E2%5C%5C%5C%5C%5Csqrt%7B66%7D%20%3D%20r%5C%5C%5C%5C%5C%5C8.12%20%3D%20r)
Answer:
See below
Step-by-step explanation:

The area of the composite figure can be calculate
120 pi x 5.1 1922.6547
1922.6547 divided by 7.4 =259.8182
259.8182 + 3.2 = 263.0182
B at least 70% i had the same question before and that was correct
