radius = 6
Answer:
37.70 units
Circle with radius 6 units
Identify the formula for circumference of a circle
Substitute the radius
Multiply
Final answer
C = 2πr
This formula calculates the perimeter of a circle.
A circular track with 6 meter radius has a 37.70 meter circumference
A wheel with 6 inch radius travels 37.70 inches per revolution
The perimeter of a circle is a fundamental concept in geometry. Perimeter measures the total distance around the outside of a 2D shape, expressed in linear units.
By using the formula C = 2πr, we can quickly and accurately calculate the perimeter for any circle when we know the required measurements.
