65 x pi = 204.2cm to one decimal place.
If that's the diameter, you can multiply that by pi (which is approximately 3.14), to get the circumference.
The circumference of a ball is C = diameter times pi. pi = 3.14159 ... So you get the circumference C = 27.4889 inches.
Circumference of pool ball: 2*pi = 6.283 inches rounded to 3 decimal places
Circumference = π x DiameterC= 3.14159 x 14C= 43.98 cm
The quickest way would be to actually measure it!Another way is to find how high/wide the ball is. This has to be done very accurately. Yoy could use parallel wooden boards (be careful not to squash the ball!The multiply the width/height of the ball by 3.14159265 (Pi).The formula is Pi x d (diameter) = circumference. A ball that is 30 cms in diameter will have a circumference of 94.248 cms.

If that's the diameter, you can multiply that by pi (which is approximately 3.14), to get the circumference.
The circumference of a ball (sphere) can be calculated using the formula ( C = \pi \times d ), where ( d ) is the diameter. For a ball with a diameter of 22 units, the circumference would be ( C = \pi \times 22 ), which is approximately 69.44 units when using ( \pi \approx 3.14 ).
The circumference of a ball is C = diameter times pi. pi = 3.14159 ... So you get the circumference C = 27.4889 inches.
Circumference = pi*d = 69 inches
65/2.54=25.59055118110236"
Circumference of pool ball: 2*pi = 6.283 inches rounded to 3 decimal places
Circumference = π x DiameterC= 3.14159 x 14C= 43.98 cm
To find the circumference of an 8 1/2 inch ball, you can use the formula for circumference, C = πd, where d is the diameter. The diameter of an 8 1/2 inch ball is 8.5 inches. Therefore, the circumference is C = π × 8.5 inches, which is approximately 26.68 inches when using 3.14 for π.
