The circumference of a circle with a diameter of 64 cm is 201 cm. Since 1 cm is equal to about 0.394 inches: 201 x 0.394 = a circumference of 79.194 inches.

Well, darling, if the circle has a diameter of 3.8 cm, then the radius would be half of that, which is 1.9 cm. It's as simple as cutting a cake in half, but without the calories. So, grab a ruler and measure that radius like the sassy math pro you are!
If a circle has a radius of 1, the diameter is 2, and the circumference is 6.28 (approximately).
-- Find the circumference of a full circle with a diameter of 12 mm.-- The perimeter of the semi-circle is(1/2 the circumference of the full circle) + (the diameter).
The circumference = (pai) x diameter = 3.14 x 1 = 3.14 cm
Circumference = pi x diameter. So the circumference of a circle with diameter 12 cm = pi x 12 = 37.7 cm (1 decimal place.)
circumference = 4.5*pi cm
The circumference of a circle with a diameter of 1 cm would be 0.31. This is used a lot in math.
You need to understand the concept of the number pi. pi is the the number of diameters you can "wrap" around a circle. The number is 3.14... So if you had a circle with a diameter of 1 cm then the circumference would be 3.14 x 1 which equals 3.14 cm Since the diameter is 14 cm the circumference is 3.14 x 14 cm The equation that deals with this is ... circumference = pi x diameter or c=pi x D
The circumference of a circle with a diameter of 64 cm is 201 cm. Since 1 cm is equal to about 0.394 inches: 201 x 0.394 = a circumference of 79.194 inches.
The circumference of any circle is (pi) x (its diameter). If diameter = 1 then Circumference = pi .
The circumference of a circle if the diameter is 1 equals 3.1412 (π).
The circumference of a circle with a diameter of 1 is Pi: 3.1416
If a circle has a circumference of 3.14 (pi) the diameter is: 1

The diameter of a circle whose circumference is 314 is about 1 (99.95).
