radius = 1
Answer:
3.14 square units
Circle with radius 1 units
Identify the formula for area of a circle
Substitute the given radius
Square the radius
Multiply by π (3.14159...)
Final answer
A = πr²
This formula calculates the area of a circle.
A circular pizza with 1 inch radius has 3.14 square inches of surface area
A circular pool with 1 meter radius covers 3.14 square meters
A round table with 1 foot radius = 3.14 square feet of table surface
The area of a circle is a fundamental concept in geometry. Area measures the amount of space inside a 2D shape, typically expressed in square units.
By using the formula A = πr², we can quickly and accurately calculate the area for any circle when we know the required measurements.
