Answer:
r = √(A/π)
Substitute area into "A", then solve:
Divide A by π, then find the square root of that number.
Explanation:
With the area of a circle, you can find the radius by rearranging its formula.
Area of a circle: A = πr²
<u>Rearrange the formula to isolate "r"</u>.
A = πr²
A/π = πr²/π Divide both sides by π
A/π = r² π divided by π cancels out on the right
√(A/π) = √r² √ both sides to cancel out ²
√(A/π) = r Write "r" on the left for standard formatting
r = √(A/π) Formula for find radius
If you have the area, use this formula.
- Substitute "A" with the area.
- Divide A by π
- Find the square root of that number
Answer:
180
Step-by-step explanation:
I need to draw a picture to explain.
Out of the given choices, the phrase that best describes a nonlinear function is letter A. The area of a circle as a function of the radius. This is because area is calculated through the equation,
A = πr²
All the rest of the choices presents linear functions.
5x - 5x + 3x - 3x = 0
****since there is one positive and one negative of both 5x and 3x everything would cancel and the equation would equal 0
