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

<h2>Greetings!</h2>

Answer:

A) 25.872

Step-by-step explanation:

A tip when multiplying numbers that are decimals, make the numbers whole numbers without decimals:

862.4 * 10 = 8624

0.03 * 100 = 3

8624 * 3 = 25,872

Then divide by the amount you multiplied the numbers by:

25,872 ÷(100 * 10) = 25.872

So your answer is A) 25.872

Answer:

T = ±22

Step-by-step explanation:

Let's solve your equation step-by-step.

0=−16t2+7744

Step 1: Add 16t^2 to both sides.

0+16t2=−16t2+7744+16t2

16t2=7744

Step 2: Divide both sides by 16.

16t2

16

=

7744

16

t2=484

Step 3: Take square root.

t=±√484

t=22 or t=−22
