Question

volume of the cylinder is 3 cm and having base area 8 square cm is​

Answer 1

Given :-

• Height of cylinder = 3 cm.
• Base area of cylinder = 8 cm².

To Find :-

• Volume of cylinder = ?

Solution :-

we know that,

• Base area of cylinder = π * (radius)² .
• Volume of cylinder = π (radius)² * h => Base Area * Height .

therefore,

→ volume of cylinder = Base Area * Height = 8 * 3 = 24 cm³. (Ans.)

Answer 2

SOLUTION

GIVEN

• The height of cylinder 3cm

• The base area 8sq cm

TO DETERMINE

Let radius of base = r cm

Height = h = 3 cm

Then

Base area =

$\sf{ = \pi {r}^{2} \: \: \: sq.cm }$

So by the given condition

$\sf{\pi {r}^{2} = 8}$

Now volume of the cylinder

$= \sf{\pi {r}^{2} h \: \: \: {cm}^{3} }$

$= \sf{\pi {r}^{2} \times h \: \: \: {cm}^{3} }$

$= \sf{8 \times 3 \: \: \: {cm}^{3} }$

$= \sf{24 \: \: \: {cm}^{3} }$

FINAL ANSWER

Hence the required volume of the cylinder

$= \sf{24 \: \: \: {cm}^{3} }$
