Question

What is the missing value? The Volume is 5120 m^3

Answer 1

32

Explanation:

V=
`\pi`r^2

5120=
`\pi r^(2)`x20

5120/20 = 256

`√(256)`=16

16+16 ( 16x2) = 32

32in.

Answer 2

I think that the missing value is 16m.

I just multiplied two other numbers with 20 and 20 x 16 x 16 = 5120

I hope this was right.
