Answer:
- Find the area of a circle that has a circumference of 175.84 inches.
☄ Given :
- Circumference of a circle = 175.84 inches
☄ To find :
- Area of a circle = ?
☄ First, we have to find :
- Radius of a circle ( r )
♨ Finding the radius of a circle :
Substitute the value of circumference of a circle
Swap the sides of the equation
⟶
Use , we obtain
Multiply : 2 by 3.14
Divide both sides by 6.28
☞ Now , we have :
- Radius of a circle ( r ) = 28 inches
Finding the area of a circle having the radius of 28 inches :
Substituting the radius , we get :
Using , we obtain :
Therefore , area of a circle is 2461.76 inches²
And we're done !
Hope I helped!
Have a wonderful time!ツ

The answer to what the length of the leg would be is 15.
You would do this problem by first writing down your Pythagorean Theorem, which is a^2 + b^2 = c^2.
Since we have our hypotenuse which is c^2 in our equation, we would write or insert the number we have.
So our equation could be that a or b leg equals 20, it doesn’t matter which one.
So we could write, 20^2 + b^2 = 25^2. So we don’t know what b leg is.
First we should figure out what 20^2 is and what 25^2 is.
20^2 is 400 and 25^2 is 625.
Our equation now comes to 400 + b^2 = 625.
Now we take 400 and subtract it from
625 -> 400 + b^2 = 625
-400.
So 625 - 400 comes out to be 225.
Lastly instead of squaring or putting 225 to the second power, we do the opposite.
So instead of squaring 225 we must square root 225. √ 225 .
The square root of √ 225 comes out to be 15.
