Question

Circumference (c) = __ d.​

Answer 1

Answer:

The circumference formula is used to calculate the distance around a circle. Circumference formulas: C = 2πr or C = πd. r is the radius and d is the diameter. The diameter is the longest chord that runs through the center of the circle.

Answer 2

Answer:

Circumference (C) = $\pi$d

Step-by-step explanation:

Circumference is the perimeter of the circle .

As we know that,

Circumference pf the circle = 2$\pi$r (where r is the radius of the circle)

Diameter ( d)= 2 r

So, when diameter is given, circumference of the circle = $\pi$ d (as 2r=d)
