Answer:
Explanation:
Remark
The formula uses the radius so that's what you have to find first.
Then rearrange the formula to find the radius.
Givens
V = 381.51
pi = 3.14
r = ?
Formula (rearranged)
r = ∛(V*3/4*pi)
Solution
r = ∛(V*3/4*pi)
r = ∛(381.51*3/4 * 3.14)
r = ∛898.45
To find the cube root use the answer and look on your calculator to find either ^ or y^x or x^y
key in 898.45 and press one of those three suggested keys.
Then key in 0.3333333 and you get
r = 9.649
That's the radius. You want the diameter
d = 2 * r
d = 2 * 9.649
Answer: d = 19.299
