Question

the volume of cylenderis 448cm^3 and height is 7 find its radius​

Answer 1

Answer:

height of the cylinder is 7 cm. Let the radius be r cm. Therefore, the radius of thecylinder is 8 cm.

Answer 2

Given :

⬤ Volume of Cylinder is 448 cm³ .

⬤ Height of Cylinder is 7 unit .

To Find :

⬤ Radius of Cylinder.

Formula Used :

$\bf[\:{Volume \: of \: Cylinder = \dfrac{1}{3} \pi{r}^{2}h}\:]$

• r = radius
• h = height

Solution :

According to the Formula :-

448 = πr²h

448 = 22/7 × r² × 7

448 = 22 × r²

448 = 22r²

448/22 = r²

20.3 = r²

√20.3 = r

4.5 = r

Therefore , Radius of Cylinder is 4.5 unit.
