Question

A rectangular sheet of paper having length 11cm ,width 4cm is rolled to form a cylinder .Find the volume of the cylinder with height 4cm​

Answer 1

Answer:

38.5 cm

Step-by-step explanation:

Answer: The volume of a cylinder with height as 4cm which is to be made of a rectangular piece of paper with dimensions 11 cm × 4 cm is 38.5 cm.

Answer 2

Answer:

$2\pi r = 11cm$

$2 \times \frac{22}{7} \times r = 11$

$r = \frac{7 \times 11}{22 \times 2}$

$\frac{7}{4} = r$

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

$\frac{22}{7} \times \frac{7}{4} \times \frac{7}{4} \times 4$

$\frac{22 \times 7}{4}$

$\frac{11 \times 7}{2}$

$5.5 \times 7$

$38.5$
