the radius of a spherical tank 0.7 meter. how many liters of water can the tank hold?

r = 0.7 m. = 70 cm.

V = (4/3)*pi*r^3.
V = (4/3)*3.148*(70)^3=1.44*10^6 cm^3.
V=1.44*10^6cm^3*1L/1000cm^3=1440 Liters

To calculate the volume of water that a spherical tank can hold, you need to know the radius of the tank. Given that the radius is 0.7 meters, we can use the formula for the volume of a sphere:

V = (4/3)πr³

Where V is the volume and r is the radius.

First, let's calculate the volume of the tank in cubic meters:

V = (4/3) x π x (0.7)^3
V ≈ 1.437 m³

Next, to convert the volume from cubic meters to liters, you need to know that 1 cubic meter is equal to 1000 liters. So you can multiply the volume by 1000:

Volume in liters ≈ 1.437 x 1000
Volume in liters ≈ 1437 liters

Therefore, the spherical tank with a radius of 0.7 meters can hold approximately 1437 liters of water.
