radius = 7
Answer:
153.9 square units
Circle with radius 7 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 7 inch radius has 153.9 square inches of surface area
A circular pool with 7 meter radius covers 153.9 square meters
A round table with 7 foot radius = 153.9 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.
