Answer 2

Step-by-step explanation:

Volume = 2898 \ cm^32898 cm3

Step-by-step explanation:

Here, we are asked to find out the volume of cylinder.

We are given its height as 21 cm and the base area as 138 sq cm.

Before solve it, just try to remember the formula of volume of cylinder.

We know it is;

Vol = \pi r^2 hVol=πr2h

In this formula, 'r' is the radius of circle (base) and 'h' is the height. (refer figure 1)

If we separate this, we get.

Vol = \pi r^2 \times hVol=πr2×h

Where, \pi r^2πr2 is the area of base and 'h' is the height.  (refer figure 2)

Now, we can say that,

Volume = Base \ area \times heightBase area×height

Thus, volume = 138 \times 21 = 2898 \ cm^3138×21=2898 cm3
