The circumference of a circle with a diameter of 14cm is: 43.98 cm
The diameter is 28cm
The diameter would be 28 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.
The diameter of a circle with an area of 37.68 is 6.92
