Question

BRAINLIEST TO RIGHT ANSWER

Answer 1

Answer:

It is A

Step-by-step explanation:

Because of the fact that the volume of it is going to be 21 cm

and 11,144 cm^3 divided by the sub coordinate is 34

then you subtract that and get 13 as your answer

Answer 2

Answer:

The radius of the cylinder is equal to $r=13\ cm$

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

In this problem we have

$V=11,144\ cm^{3}$

$h=21\ cm$

Substitute in the formula and solve for r

$11,144=\pi r^{2} (21)$

$r=\sqrt{\frac{11,144}{21\pi}}\\ \\r=13\ cm$
