Radius of two cans = 7 cm.
Height of the first can = 10 cm
Height of the second can = 20 cm

V1, Volume of first cylinder = pie r^2 h

= 22/7 *7 *7*10 =1540 cm^3

V2, Volume of 2nd cylinder = pie r^2 h

=22/7 * 7 *7*20 = 3080 cm^3

Ratio of their volumes = V1/V2 = 1540 / 3080
= 1/ 2.

◆◆◆◆step by step explanation◆◆◆◆

Base of two cylindrical can = 14cm

Radius=1/2diameter

Radius=1/2×14

Radius=7cm

Hight=10 and 20cm

Volume of cylinder=π${r}^{2}$h

Now, putting the value of both can in upon form

π${7}^{2}×10$/π${7}^{2}×20$

(All numbers are divided instead of 10/20)

10/20

1:2
