Question

in the given figure a rectangular tin foil of size 22 CM by 16 cm is wrapped around to form a cylinder of height 16 cm find the volume of the cylinder

Answer 1

HEY!!

The answer is here .

length of rectangular tin foil=22cm
breadth of rectangular tin foil=16cm.

This rectangular tin foil is wrapped to form cylinder .

Height of cylinder =16cm

Length of the rectangle will became circumference of the circle, which is base of the cylinder.

=>perimeter of circle =22cm

$= > 2\pi r = 22cm$

=> 2×22/7×r=22cm

=> r=7/2=3.5cm

$volume \: of \: cylinder = \pi {r}^{2} h$

=>22/7×3.5×3.5×16

=>616cubic. cm

pls mark as brainliest.
