What is the formula to find the area of a circle?

83. What is the formula to find the area of a circle?

1. Area = π * r
2. Area = π + r³
3. Area = r²
4. Area = π * r²

Answer

The correct answer is: D) Area = π * r²

Explanation

The formula for calculating the area of a circle is: Area = π * r²

Where "Area" is the circle's area.

• (pi) is a Mathematical constant with an approximate value of 3.14159.
• r is the radius of the circle, which is the distance squared (raised to the power of 2) from the circle's center to any point on its edge.

So, to find the area of a circle, square the radius and multiply by pi.
