What is the circumference of a circle with a radius of 66 inches?
Circumference = 3.14 x diameter Diameter = radius x 2 So...... 3.14 x 132 = 414.48
What is the Difference between the perimeteres of two concentric circles is 66 Find the difference between radius?
The formula for the circumference, (C) of a circle is C = 2πr.....where r is the radius. Let R be the radius of the larger circle and r the radius of the smaller circle. Then 66 = 2πR - 2πr = 2π(R - r) Then R - r = 66/2π = 33/π ≅ 10.504 The difference between the two radii is 10.504 (3dp)
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 diameter of a circle 66 inches in circumference?
21 inches
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.

What is the circumference of a 66 inch round circle?
circumference is the distance around the circle, so it sounds as though you are stating the circumference in your original question; 66 inches.
What is the circumference of a 21-mile circle?
The circumference of a circle with a 21 mile diameter is 66 miles (approx).
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 diameter of a circle 66 inches in circumference?
21 inches
Diameter of 66 inch circumference?
To find the diameter of a circle with a circumference of 66 inches, you can use the formula C = πd, where C is the circumference and d is the diameter. Rearranging the formula to solve for d, you get d = C / π. Plugging in the circumference of 66 inches, the diameter would be 66 / π ≈ 21 inches.

What is the circumference of a circle with a diameter of 21 feet Round to the nearest foot?
66 feet
What is the table top circumference of a 66 inch radius table?
