Circumference = 3.14 x diameter Diameter = radius x 2 So...... 3.14 x 132 = 414.48
What is the diameter if the circumference is 66 inches?
21 inches
What is the circumference of a 21-inch circle?
The circumference of a 21-inch circle is: 66 inches.(C = d x Pi).
What is the circumference of a 21-inch circle how can solve?
By a 21-inch circle I presume you mean that the diameter is 21 inches. So the radius is half as long, 10.5 inches. The formula for the circumference of a circle is 2 pi r, where r is the radius. Pi is about 3.14. That is accurate to 2 decimals, or 3 significant digits all together. I use that approximation because the dimension we are given has 2 significant digits. So the circumference is pi times the diameter; we multiply 3.14 by 21 inches and get 65.94. To 2 significant digits, that is 66 inches. If you meant that the radius was 21 inches, then the circumference would be twice as much, or 132 inches.
