A circle with radius 3 has a sector with a central angle of 1/9 pi radians

marissa [1.9K]

Complete question:

A circle with radius 3 has a sector with a central angle of 1/9 pi radians

what is the area of the sector?

Answer:

The area of the sector = $\frac{\pi}{2}$ square units

Step-by-step explanation:

To find the area of the sector of a circle, let's use the formula:

$A = \frac{1}{2} r^2 \theta$

Where, A = area

r = radius = 3

$\theta = \frac{1}{9}\pi$

Substituting values in the formula, we have:

$A = \frac{1}{2}*3^2* \frac{1}{9}\pi$

$A = \frac{1}{2}*9* \frac{1}{9}\pi$

$A = 4.5 * \frac{1}{9}\pi$

$A = \frac{\pi}{2}$

The area of the sector = $\frac{\pi}{2}$ square units

Pat shows that 16 1/2= the square root of 16. What is one possible way pat could have shown this correctly?

kifflom [539]

<h3>Answer: Choice C</h3>

The base 16 is the same as 4*4.

From there, the rule $(a*b)^c = a^c*b^c$ is used to get $(4*4)^{1/2} = 4^{1/2}*4^{1/2}$

Afterward, the exponents are added getting 1/2+1/2 = 2/2 = 1. The rule is $a^b*a^c = a^{b+c}$ which only works if the bases are both the same.
