Given:

Radius = 5 ft

To find:

The volume of the sphere

Solution:

Volume of the sphere:

$$V=\frac{4}{3}\pi r^3$

$$V=\frac{4}{3}\times 3.142 \times 5^3$

$$V=523.66$

$$V=524$

The area of a circle, in terms of π, is 80π m2. Find the value of the radius. Give your answer as a simplified surd.

jolli1 [7]

Answer:

$r=4\sqrt{5}\:\: \sf m$

Step-by-step explanation:

$\textsf{Area of a circle}=\pi r^2 \quad \textsf{(where r is the radius)}$

Given:

Area = 80π m²

Substitute the given value into the formula and solve for r:

$\implies 80 \pi = \pi r^2$

$\implies \dfrac{80 \pi}{\pi} = \dfrac{\pi r^2}{\pi}$

$\implies 80=r^2$

$\implies \sqrt{r^2}=\sqrt{80}$

$\implies r=\sqrt{80}$

$\implies r=\sqrt{16 \cdot 5}$

$\implies r=\sqrt{16}\sqrt{5}$

$\implies r=\sqrt{4^2}\sqrt{5}$

$\implies r=4\sqrt{5}$
