If the radius of the sphere above is 5 inches, what is the volume of the sphere? (Assume pi = 3.14)
V,sphere = (4/3)*pi*r^3
V,sphere = (4/3)*3.14*5^3
then solve for V. (units in inch^3)

To find the volume of a sphere, you can use the formula V = (4/3)πr^3, where V represents the volume and r represents the radius of the sphere.
Given that the radius of the sphere is 5 inches and π is approximately equal to 3.14, we can substitute these values into the formula to find the volume.
First, we cube the radius by multiplying it by itself twice: r^3 = 5^3 = 5 × 5 × 5 = 125.
Next, we substitute the values into the formula: V = (4/3) × 3.14 × 125.
Multiplying the values in the parentheses, we get: V = 1.33 × 3.14 × 125.
Finally, by multiplying the values together, we can calculate the volume: V = 523.33 cubic inches.
Therefore, the volume of the sphere is 523.33 cubic inches.
