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 radius of a circle with a 21 inch circumference?
the radius is 10.5 inches. * * * * * Wrong! Circumference = 2*pi*Radius Or, Radius = Circumference/(2*pi) So circumference = 21 inches implies radius = 3.34 inches (to 3 sf)
What is the diameter of a circle with a radius of 21 ft?
If radius=21 ft, then diameter = 2*radius = 42 ft
What is the area of a 21 mm square?
To find the area of a square, you would multiply the length of one side by itself. In this case, if the side of the square is 21 mm, the area would be 21 mm x 21 mm = 441 square mm. So, the area of a 21 mm square is 441 square millimeters.
What is the base area of a cylinder with the diameter of 21?
Its just the area of a circle 21 inches or 21 centimeters? area of a circle is (pi)*r2 where pi = 3.1415.... and r = radius thus A = (3.1415)*(diameter/2)2 u can figure out the answer from that with a calculator
