Question

Given a sphere with a diameter of 10 cm, find its volume to the nearest whole number. O A. 167 cm3 OB. 4187 cm3 O C. 524 cm3 O D. 393 cm3

Answer 1

524 cm³ (option C)

Explanation:

Volume of a sphere = 4/3 πr³

diameter = 10cm

diameter = 2(radius)

radius = diameter/2 = 10cm/2 = 5cm

let π = 3.142

$\text{Volume of the sphere = }\frac{4}{3}\times3.142\text{ }\times5^3$$\begin{gathered} \text{Volume of the sphere = }\frac{1571}{3} \\ \text{Volume of the sphere = 523.67 cm}^3 \end{gathered}$

To the nearest whole number, volume of the sphere is 524 cm³ (option C)
