Answer 1

Answer:

$\small\star{\red{\fbox{This\:is\:the\:answer}}}\star$

Step-by-step explanation:

Volume= 4/3×22÷7×(3r)³

Answer 2

Answer:

36π$r^{3}$

Step-by-step explanation:

Given,

Radius of sphere = 3r

Formula for volume of sphere = $\frac{4}{3}\pi r^{3}$

putting in the formula

$\frac{4}{3}\pi (3r)^{3}$

$=\frac{4}{3}\pi 27r^{3}$

=36π$r^{3}$
