Question

a
If the area of the circular base of a cylinder i 22000
& its height in 10cm then the volume of cylinder w​

Answer 1

Answer:

The formula of finding the volume of the cylinder is πr^2h and the area of the circular base (πr^2) is given. So, we have to find the volume of the cylinder by multiplying πr^2 with h. So, the answer will be : 220 cm^2 x 10 cm = 2200 cm^3

Answer 2

Given that,

Height of the cylinder = 10cm

Area of the circular base = 22cm^2

From this, we can find the radius using the circumference formula;

22 = πr^2

22 = 22/7 * r^2

7 = r^2

\sqrt{7}

7

= r

∵ Volume of cylinder = = πr^2h

= 22/7 * \sqrt{7}

7

* \sqrt{7}

7

* 10

= 22/7 * 7 * 10

= 220 cm^2

∵ The volume of the cylinder is 220 cm^2.
