What is the area of the shaded region?

LUCKY_DIMON [66]3 years ago

Answer:

A=5.29\pi

Step-by-step explanation:

<u>Formula for circumference of a circle is</u>:

Circumference = 2\pi r


<em>Given circumference of the ring is 4.6\pi</em>

<em>Now solving for the radius gives us:</em>

2\pi r=4.6\pi\\r=\frac{4.6\pi}{2\pi}\\r=\frac{4.6}{2}=2.3


We know that area of a circle is \pi  r^2, substituting the value of r we found, we get the area as:

area (A) = \pi r^2\\\pi (2.3)^2\\\pi (5.29)\\=5.29\pi


Hence the Area (A), in terms of \pi is 5.29\pi

The point g (2,2) is translated 3units to the right and 4units up what are the coordinates of this resulting point, g?
Svetlanka [38]

Answer:

(5,6)

Step-by-step explanation:

<em>Generally, is the coordinate (x,y) is translated right by a units and up by b units, the resulting coordinate wil be;</em>

g(X, Y)  = (x+a, y+b)

To the right is along the positive x axis while up is along the positive y axis

Given a = 3 and b = 4

g(X,Y) = (2 + 3, 2 + 4)

g(X, Y) = (5, 6)

Hence the resulting coordinate of g is (5,6)

What is the area of the shaded triangle inside the square? Round your answer to the nearest square inch.
PilotLPTM [1.2K]
Area of the triangle = 1/2 * base * <span>height 

base = 16 in
</span>height  = 16 in

Area = 1/2 * 16 * 16 = 128 in.

What is the measure of <br> A. Cannot be determined <br> B. 74<br> C. 16<br> D. 32
Levart [38]
The answer would be D. 32

Why? The triangle in the problem is an isosceles triangle. That means the two legs of the triangle are equal and the angle opposite to the equal legs are also equal. 

Therefore, angle C is also 74°. 

The sum of the interior angles of a triangle is equal to 180°.
Thus, 
      180° = ∡A + ∡B + ∡C
      180° = 74° + ∡B + 74°
      180° = 148° + ∡B
        ∡B = 180° - 148°
        ∡B = 32°

What is the arc measure of DBC in degree
aliya0001 [1]

The length of both AB and DC is the same.

19 degrees

We want to know the arc measure for the whole circle, except for DC. So, we can subtract the arc measure of DC from 360 to find DBC. Since we found DC above, all we need to do is subtract.

360 - 19 = 341

DBC = 341 degrees

Hope this helps!! :)
