I don’t think that is enough information
36:38 which would be simplified as 18:19
$3mil. To find the mean of something, you need to divide the total value (in this case, 165.5mil) by the number of elements added to get the total (55).
Volume (V) of a cylinder is the area of circular base (pi×r^2) times it's length/height (h):
![V = \pi {r}^{2} (h) \: \: \pi = 3.14](https://tex.z-dn.net/?f=%20V%20%3D%20%20%5Cpi%20%7Br%7D%5E%7B2%7D%20%28h%29%20%5C%3A%20%20%5C%3A%20%5Cpi%20%3D%203.14)
h = 20.5 ft
diameter (d) = 1 1/5 × h, 1 1/5 = 6/5 = 1.20
d = 1.20 × 20.5 = 24.6 ft
radius (r) = 1/2 d = 24.6/2 = 12.3 ft
I think its the first one but i'm not 100% sure, don't trust me
