The area of the shaded sector is shown. Find the radius of circle M. Round your answer to the nearest hundredth.

Vaselesa [24]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the sector, its area and the angle at the center are not given.

I will solve this using the following illusration

The area of a sector is:

$Area= \frac{\theta}{360} * \pi r^2$

Assume that:

$\theta = 120$

$Area = 20$

The equation becomes

$20= \frac{120}{360} * \pi r^2$

Simplify

$20= \frac{1}{3} * \pi r^2$

Take: $\pi = 3.14$

$20= \frac{1}{3} *3.14* r^2$

Cross Multiply

$3.14 * r^2 = 20 * 3\\$

Solve for $r^2$

$r^2 = \frac{20 * 3}{3.14}$

$r^2 = 19.11$

Take square roots

$r = \sqrt{19.11$

$r = 4.4$

What is the solution set? Enter your answer in the box

Xelga [282]

Answer:

$x>3$

The solution set is $(3, infinite)$

Step-by-step explanation:

we have

$5.5x+15.5>32$

Solve for x

Subtract $15.5$ both sides

$5.5x+15.5-15.5>32-15.5$

$5.5x>16.5$

Divide by $5.5$ both sides

$5.5x/5.5>16.5/5.5$

$x>3$

The solution is the interval-------> $(3, infinite)$

All real numbers greater than $3$
