The circumference of a circle is givn by the equation Pi x r squared. Pi is always 3.147, r stands for radius, which is half the diameter( it just is ;) and squared is an arithmntic function where one multiplies a value by itself. So to calculate your answer...
3.147 x ((10.5/2) x (10.5/2)) = 86.73 (cm)

What is the circumference of a circle if the diameter is 105 cm?
The diameter would be about 329.9 cm
What is the circumference of a circle 13cm diameter?
Diameter = Circumfrence/pi = 13/pi = 4.14 cm (approx)
The diameter of a circle is 105 cm less than the circumference What is the diameter of the circle?
The formula to calculate the circumference of a circle is C = 2πr = πD D, the diameter of the circle is C - 105. Therefore C = π (C - 105) = πC - 105π πC - C = 105π : C(π - 1) = 105π C = 105π/(π - 1)............as C = πD then πD = 105π/(π - 1) D = 105/(π - 1) = 49.03 ( to 2 decimal places) The diameter of the circle is 49.03 cm
What is a baseballs circumfrence?
a MLB baseball's diameter is 3". circumference = pi * diameter = 3.141 * 3" = 9.4" (23.7 cm)

What is the radius of a circle with a diameter of 15 cm?
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
The diameter of a circle is 12 cm what is its radius?
If the diameter is 12 cm the radius is 6 cm.
What is a circle's diameter if the radius is 7 cm?
The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.
What is a baseballs circumfrence?
a MLB baseball's diameter is 3". circumference = pi * diameter = 3.141 * 3" = 9.4" (23.7 cm)
What is the radius of a circle with a 6.2 cm diameter?
The radius (radii) of a circle is 1/2 of the diameter. The radius of a circle with a 6.2 cm diameter is 3.1 cm.
What is the circumference of a circle with the diameter of 2.7 cm?
The circumference of a circle with the diameter of 2.7 cm is 8.5 cm
What is the circumference of a circle with a diameter of 12 cm?
The circumference of a circle with a diameter of 12 cm is: about 37.7 cm
What is a diameter of a circle with a circumference of 45 cm?
The diameter of a circle with a circumference of 45 cm is: about 14.32 cm
If the circumference of a circle is 30 cm what is the diameter?
If the circumference of a circle is 30 cm its diameter is: 9.549 cm
