Answer:

First choice V = 18,432π m^3; S = 2,304π m^2

Explanation:

Start with the two formulas:

Volume of a circle:

$V = (4)/(3) \pi r^3$

Surface area of a circle:

$S = 4 \pi r^2$

Now use r = 24 m in each formula.

Volume:

$V = (4)/(3) \pi (24~m)^3$

$V = (4)/(3) \pi (13,824~m^3)$

$V = 18,432\pi~m^3$

Surface area:

$S = 4 \pi r^2$

$S = 4 \pi (24~m)^2$

$S = 4 \pi (576~m^2)$

$S = 2,304\pi ~m^2$

Answer: First choice V = 18,432π m^3; S = 2,304π m^2
