Answer:

Question 1 )

given ,

height of cylinder = 9 cm

diameter of cylinder = 10 cm

$\dashrightarrow \: radius = \frac{10}{5} \: cm \\$

now ,

$Volume \: of \: cylinder = \pi \: r {}^{2} h \\ \\ substitutng \: the \: values \: of \: h \: and \: r \: \\ \\ \dashrightarrow \: \pi \: \times (\frac{10}{2} ) {}^{2} \times 9 \\ \\ \dashrightarrow \: \pi \: \times 25 \times 9 \\ \\ \dashrightarrow \: 225\pi \: cm {}^{3}$

therefore ,

option (C) is correct.

Question - 2 )

dimensions of the rectangular prism are 2 × 3 × 4

$Lateral \: surface \: area = 2h(l + b) \\ \\ \dashrightarrow \: 2 \times 3(4 + 2) \\ \\ \dashrightarrow \: 6(6) \\ \\ \dashrightarrow \: 36 \: cm {}^{2}$
