Circumference of a circle is 630 mm, what will the diameter be?

1.64 ( C=pi D circumference is equal to pi times the Diameter. Diameter is equal to the circumference divided by pi. pi is 3.14. 5.14 divided by 3.14 is 1.64.)

If you would like to know the circumference of a 15" diameter circle this is the formula:
circumference = radius x 2 x pi
circumference = diameter x pi

in our case:
circumference = 15" x 3,14
circumference = 47 ,1" (that's 119,634 cm)

The circumference of any circle is pi (lowercase Greek letter pi) multiplied by the diameter. For a four-foot diameter circle the circumference is about 12 feet 7 inches.

The circumference of any circle is pi (lowercase Greek letter pi) multiplied by the diameter. For a four-foot diameter circle the circumference is about 12 feet 7 inches.

The circumference of any circle is pi (lowercase Greek letter pi) multiplied by the diameter. For a four-foot diameter circle the circumference is about 12 feet 7 inches.

The formula is simply this: C = (pi)d. In this equation, "c" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi, which is an approximation of 3.14.

The circumference (C) of a circle and its diameter (D) are related by
C=PI*D (Pi is the famous constant)
D=C/Pi

Yes, you'll be o.k. They don't recommend anything over 3% difference, and your at about 1.8%. Speedo will read 61 mph when actually doing 60 mph. Have a look.

what class are you in? Is this your home work? Anyway, You should know that
Circumference = 2 x pie x radius therefore radius - circumference / 2 x pie in this case radius = 30 x 7 / 2 x 22 = 210 / 44 Now you can calculate that fraction.

You cannot have a semicircle that has a diameter of 2.500 mm and a radius of .425mm and a circumference of 3000mm

Circumference is equal to pi times the diameter. pi is = 3.14

The radius of a circle is always 1/2 the diameter

Area of a circle is pi time the radius squared
