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:

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

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

$\implies 80=r^2$

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

$\implies r=\sqrt{80}$

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

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

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

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

If the hypotenuse of a right triangle is 6 feet long, and one leg is 5 feet long,

Anestetic [448]

C^2=a^2+b^2
6^2=5^2+b^2
36=25+b^2
b^2=36-25
b^2=11
b= √11
b=3.3166
If you need to round it to the tenth place,
b~3.3
to hundreds place,
b~3.32
Good luck
