Question

find area and circunference of a circle​

Answer 1

Answer:

To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π=3.14)...

Area of circle can be calculated by using the formulas:

Area = π x r2, in terms of radius 'r'.

Area = (π/4) x d2, in terms of diameter, 'd'.

Area = C2/4π, in terms of circumference, 'C'.
