Question

volume= 308cm^3
height=8 cm
find radius of the cylinder....

please

Answer 1

Answer:

This is indirect question of finding volume of Cylinder.

given that height of the cylinder is 8 cm.

ln this question volume and height are given and we have to calculate the radius using volume and height.

We can calculate it as shown below:-)

$Volume = 308 {cm}^{3}$

As we know that

$Volume = \pi {r}^{2} h$

So ,

$\pi {r}^{2} h = 308 \\ \implies \frac{22}{7} \times {r}^{2} \times 8 = 308 \\ \implies {r}^{2} = \frac{308 \times 7 }{22\times 8 } \\ \implies {r}^{2} = \frac{49}{4} \\ \implies r=\frac{7}{2} \\ \implies r=3.5 cm$

Answer 2

Answer:

Hello mate.

here is the answer.

We can find the question by putting the formula of volume.

$\pi {r}^{2} h = 308 \\ r = \sqrt{ \frac{308 \times7 }{22 \times 8} } \\ = \sqrt{ \frac{49}{4} } \\ = \frac{7}{2} \\ = 3.5cm$

so radius of the cylinder will be 3.5 CM
