Answer 1

$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's solve ~

We need to find volume of the given Cylinder, with information :

• radius (r) = 12 units

• height (h) = 17 units

$\qquad \sf  \dashrightarrow \:Volume_{(Cylinder)} = \pi r²h$

$\qquad \sf  \dashrightarrow \:Volume_{(Cylinder)} = \pi \sdot(12) {}^{2} \sdot17$

$\qquad \sf  \dashrightarrow \:Volume_{(Cylinder)} = \pi \sdot144{}^{} \sdot17$

$\qquad \sf  \dashrightarrow \:Volume_{(Cylinder)} = 2448 \pi \: \: unit {}^{3}$

So, correct choice is B

Answer 2

• r=12
• h=17

Volume

• πr²h
• π(12)²(17)
• π(144)(17)
• 2448π units²
