What is the radius of a circle with an area of 49 pi

Mathematics
1 answer:
Elenna [48]3 years ago
3 0

Answer:

r = 7

Step-by-step explanation:

The area of a circle is given by the equation A = πr²

We need to manipulate the equation and solve for r

First we need to divide both sides by π and we get \frac{A}{\pi } =r^{2}

We then need to take the square root of both sides to get r by itself which give us r=\sqrt{\frac{A}{\pi } }

Now plugging in our known values we can solve for r

r=\sqrt{\frac{49\pi }{\pi } }=\sqrt{49} =7

Simplifying gives us the result of the radius being 7 square units

Billy, let's recall what a linear pair of angles is:

• They are formed when two lines intersect.

,

• Two angles are said to be linear if they are adjacent angles formed by two intersecting lines.

,

• The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

Upon saying that we have that:

• CAD and DAE are linear pairs

,

• CAD and CAB are linear pairs

,

• DAE and BAE are linear pairs

,

• DAE and DAC are linear pairs

Now, you are ready to select all the options that actually apply.
