Find the volume of a sphere with a diameter of 8 cm. (Use 3.14 for pi.) 189 cm³ 258 cm³ 159.9 cm³ 267.95 cm³

Gemiola [76]

Answer:

267.95 cm³ (nearest hundredth)

Step-by-step explanation:

<u>Formulae</u>

$\textsf{Volume of a sphere}=\sf \dfrac43 \pi r^3\quad\textsf{(where r is the radius)}$

$\textsf{Diameter of a circle}=\sf 2r\quad\textsf{(where r is the radius)}$

Given:

diameter = 8 cm
$\pi$ = 3.14

⇒ radius = 8 ÷ 2 = 4cm

$\begin{aligned}\implies \textsf{Volume} &=\sf \dfrac43 \cdot 3.14 \cdot 4^3\\ & = \sf 267.95\:cm^3\:(nearest\:hundredth)\end{aligned}$
