The circumference of a circle with a diameter of 14cm is: 43.98 cm
If what is 14cm? The diameter? The circumference?d = diameter, r = radius, C = circumference, A = area, pi = approx. 3.14If d = 14cm, then r = 7cm.A = (pi)r2 = (pi)(7)2 = (3.14)(49) = 153.86 = about 154cm2.If C = 14cm, use the formula C = 2(pi)r:14 = 2(pi)rr = 14/(2pi) = 14/6.28 = about 2.229 = about 2.23cm.Then A = (pi)r2 = (3.14)(2.229)2 = 3.14(4.970) = about 15.6 cm2.
If that's the diameter, you can multiply that by pi (which is approximately 3.14), to get the circumference.
The circumference of a ball is C = diameter times pi. pi = 3.14159 ... So you get the circumference C = 27.4889 inches.
The diameter is 28cm

The question cannot be answered. There is no information on what aspect of the cylinder is 14 cm: the radius, diameter, circumference, height.
Assuming that "it" refers to diameter, the radius is 7 cm and the circumference is 44.0 cm.
Area = pi*72 square cm Circumference = pi*14 cm
C=2 pi R
Circumference = 2*pi*radius or pi*diameter Circumference = 87.9645943 or 88 cm to the nearest cm

First, we should note that the formula for circumference is Dπ, or diameter times pi. Second, we should note that the diameter is simply double the radius. With this in mind, the circumference formula can then be turned into (2r)π C=2(14)π C=28π which is about equal to 87.96459
