Question

What is the volume of a sphere with a diameter of 7.6 cm, rounded to the nearesttenth of a cubic centimeter?

Answer 1

Given:

Diameter = 7.6 cm

To find the volume of the sphere, use the formula below:

`V\text{ = }(4)/(3)\pi r^3`

Where,

π = 3.142

r = diameter/2

`r\text{ = }(d)/(2)=\text{ }(7.6)/(2)\text{ = }3.8\text{ cm}`

Volume of the sphere:

`\begin{gathered} V\text{ = }(4)/(3)\pi r^3 \\ \\ \text{ = }(4)/(3)\ast3.142\ast3.8^3 \\ \\ \text{ = }229.9cm^3 \end{gathered}`

ANSWER:

`V=229.9cm^3`
