I got 50.24
since 2*3.14*8=50.24

Answer:
4 to the sixth power
Step-by-step explanation:
When multiplying exponents with the same base, you can add their powers.
Given:
volume of larger cone : 8000 m³
radius of larger cone: 5 m
radius of smaller cone: 2 m
volume of smaller cone: ?
Find the volume of the smaller cone using the ratio of the volumes.
a / b = c / d where ad = bc
5m / 8000 m³ = 2 m / x
5m * x = 8000 m³ * 2m
5m * x = 16000 m⁴
x = 16000 m⁴ / 5m
x = 3200 m³
