Question

the base area of a cylinder is 20 square CM and the height is 5 CM what is the value of the cylinder​

Answer 1

Answer:

given,

base area= πr^2 = 20cm^2

height = 5cm

Step-by-step explanation:

volume= πr^2h

= 20*5

= 100cm^3

Answer 2

Appropriate question:

• the base area of a cylinder is 20 cm² and the height is 5cm what is the volume of the cylinder

Given:

• The base area of the cylinder is 20cm² and the hieght of the cylinder is 5cm

To Find:

• The volume of the cylinder?

Solution:

We know that,

$\star \: { \underline{ \boxed{ \frak{volume \: of \: a \: cylinder = \pi {r}^{2} h}}}}$

Where,

• π stands for 22/7
• R stands for radius
• h stands for hieght

Here,

• We have the hieght of the cylinder and the base area of the cylinder , we have to multiply the base area with the hieght to find the volume

${ \underline{ \frak{As \: we \: know \: that}}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \star{ \underline{ \boxed{ \sf{base \: area _{(cylinder)} = \pi \: {r}^{2} }}}}$

Substituting the values we get,

${ : \implies} \sf\: volume _{(cylinder)} = base \: area \times hieght \\ \\ \\ { : \implies} \sf\: volume _{(cylinder)} = 20 {cm}^{2} \times 5cm \\ \\ \\ { : \implies} \sf\: volume _{(cylinder)} = {\boxed{ \tt{100 {cm}^{3} }}}$

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

Therefore,

• The volume of the cylinder is 100cm³

More to know:

• Volume of a cube = side³
• Volume of a cubiod = l × b × h
• Total surface area of a cubiod = 2(hl+lb+bh)
• Total surface area of a cube = 4(side)²
• Curved surface area of the cylinder = 2πrh
• Total surface area of a cylinder 2πrh + 2πr²
