Question

The equation πr²Gives the area,A of a circle with a radius,r,. Solve the function for π

Answer 1

The solution of the function for π is $\pi =\frac{A}{r^{2}}$

Step-by-step explanation:

The equation πr² gives the area A of a circle with a radius r

To Solve the function for π

• Write the function
• Keep π in one side and all other terms in other side by using any operation you need (+ , - , × , ÷)

∵ A = πr²

- You need to take r² from the right hand side to the left hand

   side to keep π in the right hand side alone

∵ r² is multiplied by π

∴ Divide both sides by r²

∴ $\frac{A}{r^{2}}=\frac{\pi .r^{2}}{r^{2} }$

∴ $\frac{A}{r^{2}}=\pi$

- Switch the two sides

∴ $\pi =\frac{A}{r^{2}}$

The solution of the function for π is $\pi =\frac{A}{r^{2}}$
