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

Answers

Answer 1

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:

[tex]Area= \frac{\theta}{360} * \pi r^2[/tex]

Assume that:

[tex]\theta = 120[/tex]

[tex]Area = 20[/tex]

The equation becomes

[tex]20= \frac{120}{360} * \pi r^2[/tex]

Simplify

[tex]20= \frac{1}{3} * \pi r^2[/tex]

Take: [tex]\pi = 3.14[/tex]

[tex]20= \frac{1}{3} *3.14* r^2[/tex]

Cross Multiply

[tex]3.14 * r^2 = 20 * 3\\[/tex]

Solve for [tex]r^2[/tex]

[tex]r^2 = \frac{20 * 3}{3.14}[/tex]

[tex]r^2 = 19.11[/tex]

Take square roots

[tex]r = \sqrt{19.11[/tex]

[tex]r = 4.4[/tex]

Answer 2

The radius of the sector of a circle whose area is 20 square units and angle subtends at the center of 120° is 4.4 units.

What is a circle?

It is a locus of a point drawn equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The angle subtends at the center is 120 degrees.

The area of the circle is 20 units.

We know that the area of a circle is given  as

[tex]\rm Area = \dfrac{\theta }{360} \pi r^2[/tex]

Then we have the radius of the sector will be

[tex]\rm r = \sqrt{\dfrac{360*20}{120*\pi}}\\\\\\r = 4.37 \approx 4.4[/tex]

The radius of the sector is 4.4 units.

The length of a dog run is twice its width. Its area is 50 square yards.
Find the length and width of the dog run.

Answers

Answer:

Length = 10 yards Width = 5 yards

Step-by-step explanation:

2w x w = 50 yards²

2w² = 50 yards²

2w²/2 = 50 yards² / 2

[tex]\sqrt{w^{2} }[/tex] = [tex]\sqrt 25 yards^{2}[/tex]

w = 5

Area = l x w

= 10 x 5 = 50

length = 2w

width = w

length = 2(5)

length = 10 yards

Which of the following do not represent the measures of the sides of a triangle?
A)57, 80, 24
B) 43, 133, 89
C) 5, 6, 7
D 20, 20, 30

Answers

Answer:     B) 43, 133, 89

===========================================================

Explanation:

For this answer choice, we have p = 43, q = 133, and r = 89. Note how p+r = 43+89 = 132, which is not larger than the third remaining side q = 133. Therefore, p+r > q is false and a triangle cannot be formed.

A triangle is only possible if and only if adding any two sides leads to a sum larger than the third side (triangle inequality theorem).

Put another way, we must have these three conditions hold true for a triangle to form:

p+q > rp+r > qq+r > p

If any of those three are false, then we cannot make a triangle with side lengths p,q,r

-----------------

Let's go over choice C for an example in which we can form a triangle

p = 5, q = 6, r = 7

We can see that,

p+q = 5+6 = 11 which is greater than r = 7. So p+q > r is true.p+r = 5+7 = 12 which is greater than q = 6. So p+r > q is true.q+r = 6+7 = 13 which is greater than p = 5. So q+r > p is true.

All three conditions are true, and therefore we have a triangle that is possible with side lengths p = 5, q = 6, r = 7. I recommend cutting out slips of paper with these lengths to try it out yourself, so you have a real world example to play with. Choices A and D are a similar story to choice C, so we can rule out all three of these choices.

Step-by-step explanation:

250+2x=360

2x=110

x=55

Answer:

55

Step-by-step explanation:

There are many ways to solve this problem; however, I used the one I believe to be the fastest and easiest, but you can still use a different way.

I solved this by using the fact that the green angle (m<125) and the red angle (x) make a straight line. All straight lines equal 180 degrees; therefore, this line must equal 125+x=180. Then, you can subtract 125 from both sides of the equation. That leaves x=55.
