Answer 2

45,994 liters is the capacity of the hemispherical tank in liters.

Step-by-step explanation:

Given that,

The inner radius of a hemispherical tank = 2.8 m

∴ The capacity of hemispherical tank =  2/3πr^3

= 2/3 * 22/7 * (2.8)^3

= 2/3 * 22/7 * 21.952

= 45.994m^3(approx.)

As we know, {1m^3 = 1000 liters}

∴ The capacity would be = 45.994 * 1000

= 45,994.66 liters
