Question

Translate the following sentence into a formula:

“The area of a circle is the product of $\pi$ and the radius  squared”.

 

Step-by-Step Solution

Answer

The formula is $A=\pi r^2$.

Step 1. Given information.

The given sentence is:

The area of the circle is the product of $\pi$ and the square of radius.

Step 2. Mention the algebraic variables.

Consider the Area of the circle is A and the radius of the circle be r.

Step 3. Write the formula.

Since the square of radius is $r^2$.

Therefore, the formula becomes:

$A=\pi r^2$
