What is the volume of a sphere having a diameter of 6 cm?

113.1

Step-by-step explanation:

Volume of sphere = × π × r²

Volume of sphere =   × π × 3²

Volume of sphere =   × π × 9

Volume of sphere =   × 9 π

Volume of sphere = 113.1

Step-by-step explanation:

The formula to calculate the volume of a sphere is:

Where r is the radius of the sphere.

In this case we do not know the radius of the sphere, but we know the diameter.

By definition the diameter of a sphere is equal to twice the radius. This is:

In this case d=6 cm

So

Finally

b. x + 1
