Question

A sphere has a radius of 4.5 cm. What is the volume of the sphere? round to the nearest hundredth.

Answer 1

381.70 cm³

Step-by-step explanation:

The volume of a sphere can be calculated as

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

Where π = 3.1415 and the radius r = 4.5 cm. So, the volume is calculated as

`\begin{gathered} V=(4)/(3)(3.1415)(4.5cm)^3 \\ V=(4)/(3)(3.1415)(91.125cm^3) \\ V=381.70cm^3 \end{gathered}`

Therefore, the volume of the sphere is 381.70 cm³
