Caitlyn bought a helium tank to fill spherical balloons for a party. If the diameter of the filled balloons are 14.4 inches, how much helium would be needed in each balloon?

radius of each balloon = 7.2 inches

Volume of each balloon = (4/3)πr^3
= (4/3)π(7.2)^3
= appr 1563 cubic inches

Find it put on your own. Don't cheat lol

To calculate the amount of helium needed in each balloon, we need to use the formula for the volume of a sphere. The volume of a sphere is given by:

V = (4/3) x π x r^3

where V is the volume and r is the radius of the sphere.

Given that the diameter of the filled balloons is 14.4 inches, we can find the radius by dividing the diameter by 2:

r = 14.4 inches / 2 = 7.2 inches

Now we can substitute the radius into the volume formula:

V = (4/3) x π x (7.2 inches)^3

Calculating this expression will give us the volume of helium needed for each balloon.
