radius = 25
Answer:
1963.5 square units
Circle with radius 25 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 25 inch radius has 1963.5 square inches of surface area
A circular pool with 25 meter radius covers 1963.5 square meters
A round table with 25 foot radius = 1963.5 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.
