Given:
A sphere whose radius has length 5 m.
Required:
(a) Approximate surface area in square meters
(b) Approximate volume in cubic meters.
Explanation:
We know
[tex]\begin{gathered} \text{ Area of sphere }=4\pi r^2 \\ \text{ Volume of sphere = }\frac{4}{3}\pi r^3 \end{gathered}[/tex]
We have radius = 5m
So,
[tex]\begin{gathered} A=4\pi r^2 \\ A=4\times\pi\times5^2 \\ A=314.16\text{ }m^2 \end{gathered}[/tex]
And volume
[tex]\begin{gathered} V=\frac{4}{3}\pi r^3 \\ V=\frac{4}{3}\times\pi\times5^3 \\ V=523.6\text{ }m^3 \end{gathered}[/tex]
Answer:
Area is 314.16 meter square and volume 523.56 meter cube.
