The perimeter or circumference of a circle = 2*pi*radius or pi*diameter
Chat with our AI personalities
If you mean the circumference or "perimeter": C = 2(pi)r, where r is the radius of the circle
Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
The circumference of a circle represents its perimeter and the distance around it.
yes u can calculate the perimeter of a trapezium
If 'R' is the radius of the circle, then-- area of the circle is [ pi R2]-- perimeter of the circle is [ 2 pi R ]
