If that's the diameter, you can multiply that by pi (which is approximately 3.14), to get the circumference.
The circumference of a 55 centimeter ball is: 172.8 cm(c = d x Pi)
Circumference is Pi x d so it is 55 Pi which is roughly 172.7 cm
Circumference = π x DiameterC= 3.14159 x 14C= 43.98 cm
The circumference of a 7 cm circle is: 21.99 cm(diameter x pi = circumference).
The circumference of circle that is 8 cm is: about 25.13 cm (diameter x pi = circumference).
The circumference of a 55 centimeter ball is: 172.8 cm(c = d x Pi)
The ball is about 11 inches (28 cm) long and about 22 inches (56 cm) in circumference at the center.
it is usually between 7.75 and 8 inches (19-20 cm) in circumference (about 2.5 inches (6.5 cm) in diameter)
172.8
30 inches diameter or 93 inches circumference
The ball is about 11 inches (28 cm) long and about 22 inches (56 cm) in circumference at the center.
The ball is about 11 inches (28 cm) long and about 22 inches (56 cm) in circumference at the center.
Circumference is Pi x d so it is 55 Pi which is roughly 172.7 cm
Men - 29.5 inches (74.9 cm) in circumference 22 ounces (624 g) in weight Women - 28.5 inches (72.4 cm) in circumference 20 ounces (567 g) in weight
The circumference of a circle with a diameter of 64 cm is 201 cm. Since 1 cm is equal to about 0.394 inches: 201 x 0.394 = a circumference of 79.194 inches.
If the ball makes 12 rotations in 10 meters, then 1 rotation takes 83.3 cm. This would equal the circumference of the ball. Then the diameter would be 26.5 cm (or 10.43 inches). This is significantly larger than a regulation soccer ball, which must have a circumference between 68 and 70 cm.
For men, the official ball is 29.5 inches (74.9 cm) in circumference (size 7, or a "295 ball") and weighs 22 ounces (624 g). If women are playing, the official basketball size is 28.5 inches (72.4 cm) in circumference (size 6, or a "285 ball") with a weight of 20 ounces (567 g).
