The diameter of the circle is 63cm what is circumference?

The circumference of a circle can be calculated using the formula:

Circumference = π x diameter

Given that the diameter of the circle is 63 cm, we can substitute this value into the formula:

Circumference = π x 63 cm
Circumference = 3.14159 x 63 cm
Circumference ≈ 197.92 cm

Therefore, the circumference of the circle is approximately 197.92 cm.

The circumference of a circle is given by the formula:

C = πd

where C is the circumference, π is a mathematical constant approximately equal to 3.14159, and d is the diameter of the circle.

Given that the diameter of the circle is 63 cm, we can calculate the circumference as follows:

C = πd
= 3.14159 - 63 cm
≈ 198 cm

Therefore, the circumference of the circle with a diameter of 63 cm is approximately 198 cm.
