PSAT Math › How to find the radius of a sphere
If a sphere has a volume of , then what is the radius of the sphere?
A cube with volume 27 cubic inches is inscribed inside a sphere such that each vertex of the cube touches the sphere. What is the radius, in inches, of the sphere?
The Kelvin temperature scale is basically the same as the Celsius scale except with a different zero point; to convert degrees Celsius to Kelvins, add 273. Also, by Charles's law, the volume of a given mass of gas varies directly as its temperature, expressed in Kelvins.
In the early morning, when the temperature is , a spherical balloon is filled with helium until its radius is 100 meters. At 2:00 PM, the temperature is
. To the nearest tenth of a meter, what is the radius of the balloon at this time?

A spherical balloon is filled with 10,000 cubic meters of gas in the morning when the temperature is . The temperature increases to
by noon, with no other conditions changing. What is the radius of the balloon at noon, to the nearest tenth of a meter?
The city of Washington wants to build a spherical water tank for the town hall. The tank is to have capacity 120 cubic meters of water.
To the nearest tenth, what will the radius of the tank be?
A spherical tank is to hold 50,000 liters of water. Given that one cubic meter is equal to 1,000 liters, give the radius of this tank to the nearest tenth of a meter.
The surface area of a sphere is 100π square feet. What is the radius in feet?
A spherical water tank has a surface area of 400 square meters. To the nearest tenth of a meter, give the radius of the tank.
