Question

May someone please help? thank you!

Answer 1

Answer:

$6\sqrt2\\OR\\8.48528137$

Step-by-step explanation:

The area of a sector of a circle is found by:

$A = \frac{\theta*r^2}{2}$

The question asks for the radius so the equation above can be repurposed

$r = \sqrt\frac{2A}{\theta}$

A = 3pi

angle = pi/12

$\frac{6\pi}{\pi/12} = \frac{72\pi}{\pi} = 72$

$\sqrt{72} = 6\sqrt2 = 8.48528137$
