Answer 1

Given

• 1.Radius = 2 cm, ht=4 cm,
• 2.Diameter = 16 ft, ht = 26 ft
• 3.Diameter = 2m, ht = 21m
• 4.Diameter =2 cm, ht =16cm,
• 5.Radius = 9m, ht =15 m

To Find

• Volume of Cylinder

Formula used

$\underline{ \boxed{\sf{ \: \: \: \: \: \: \: \: \: \: \: Volume \: of \: Cylinder= πr²h \: \: \: \: \: \: \: \: \: }}}$

Step by step explanation :

_____________________

1 Radius= 2cm height=4cm

$\sf Volume \: of \: Cylinder= πr²h$

$\sf Volume \: of \: Cylinder= \frac{22}{7} \times 2² \times4$

$\sf Volume \: of \: Cylinder= \frac{22}{7} \times 16$

$\sf Volume \: of \: Cylinder= 3.14 \times 16$

$\sf \pink{Volume \: of \: Cylinder = 50.24 \: {cm}^{3} }$

_____________________

2 Diameter = 16 ft, ht = 26 ft

Or Radius= 8ft ,Height= 26ft

$\\\\ \sf Volume \: of \: Cylinder= \frac{22}{7} \times 8² \times 26$

$\sf Volume \: of \: Cylinder= 3.14 \times 64 \times 26$

$\sf Volume \: of \: Cylinder= 3.14 \times 1664$

$\sf \pink{Volume \: of \: Cylinder= 5225 \: {ft}^{3} }$

_____________________

3 Diameter = 2m, ht = 21m

Or Radius= 1m ,Height= 21m

$\\\\\sf Volume \: of \: Cylinder= \frac{22}{7} \times 1² \times 21$

$\sf Volume \: of \: Cylinder= 22 \times 3$

$\sf \pink{Volume \: of \: Cylinder= 66 {m}^{3} }$

_____________________

4 Diameter =2 cm, ht =16cm,

Or Radius= 1cm ,Height= 16cm

$\\\sf Volume \: of \: Cylinder= \frac{22}{7} \times 1² \times 16$

$\sf Volume \: of \: Cylinder= \frac{22}{7} \times 16$

$\sf Volume \: of \: Cylinder= 3.14 \times 16$

$\sf \pink{Volume \: of \: Cylinder= 50.24 {cm}^{3} }$

_____________________

5 Radius = 9m, ht =15 m

$\\\sf Volume \: of \: Cylinder= \frac{22}{7} \times 9² \times 15$

$\sf Volume \: of \: Cylinder= 3.14 \times 81 \times 15$

$\sf Volume \: of \: Cylinder= 3.14 \times 1215$

$\sf\pink{ Volume \: of \: Cylinder= 3815 {m}^{3}}$
