The perimeter of a circle is equal to pi times the diameter, so for a circle with a diameter of 14 cm, multiply by pi, which is approximately 3.14, and you get 43.96 cm, which for most purposes you could round off to 44 cm.
Circumference is (pi x diameter of circle). (Diameter is the distance across the circle, going through the very centre. It is also twice the radius, which is the distance from the middle of the circle to the outer edge). In the question you don't indicate what the 14cm is (i.e. diameter/radius ?), so I can't work it out for you.
The question cannot be answered. There is no information on what aspect of the cylinder is 14 cm: the radius, diameter, circumference, height.
Area of circle = πr2 Exact area = π(14)2 = 196π cm2
14cm and 11cm what is the missing side using pythagorean theorem
The perimeter is the total distance around a two-dimensional shape. To find the perimeter of a shape, you need to add up all the lengths of its sides. In this case, the perimeter of a shape with sides measuring 5cm and 2cm would be 5cm + 5cm + 2cm + 2cm = 14cm.
The diameter is 28cm
The diameter would be 28 cm.
Assuming that "it" refers to diameter, the radius is 7 cm and the circumference is 44.0 cm.
The circumference of a circle with a diameter of 14cm is: 43.98 cm
C=2 pi R
14(22/7+2) =2(22+2) =44+4 =48
Circumference = 2*pi*radius or pi*diameter Circumference = 87.9645943 or 88 cm to the nearest cm

The radius is: 6.267 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.
pi*72 = 153.93804 or about 154 square cm
