Question 1 and 2 in attachments.

Question 3.

Volume of cylinder =

$\pi {r}^{2} h \: \: \: \: \: \: ....(1)$

ATQ

$\pi \times {(2r)}^{2} \times h$

$\pi \times 4 \times {r}^{2} \times h$

FROM (1)

$4(\pi {r}^{2} h)$

So, if the radius of cylinder is doubled, the volume is quadrupled.

Answer 2

3 will be option no. d
