Question

Find its volume. Use 3.14 as the approximate value of a25 m

Answer 1

we know that

the solid of the figure is a sphere

the volume of the sphere is equal to

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

we have

pi=3.14

r=25 m

substitute

`\begin{gathered} V=(4)/(3)\cdot3.14\cdot25^3 \\ V=65,416.67\text{ m\textasciicircum{}3} \end{gathered}`

the volume of the sphere is 65,416.67 cubic meters
