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 circumference of a circle with a diameter of 14cm is: 43.98 cm
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
