It is the length of its circumference
20 inches
If I understand the question, it would be once. I understand the situation to mean that if you had two footballs of the same size and rolled one around the middle of the other, how many times would you see the laces straight up basically (how many rotations)? Since the radii are the same it would just go through one rotation, covering its circumference in distance and since this is the circumference of the other ball it would be finished rotating. It's hard to show without a picture.
Circumference = 2pi*r Circumference = 86pi
circumference of the tire.
It is the length of its circumference
20 inches
The football is 27cm in long and 60 cm in circumference.
Circumference of 27-28 Inches!
68 - 70 cm in circumference.
The football is 27cm in long and 60 cm in circumference.
if any part of the football is over the chains then the answer is first down
The dimensions of an NFL football are: long axis: 11 to 11.25 inches long circumference: 28 to 28.5 inches short circumference: 21 to 21.25 inches weight: 14 to 15 ounces inflation: 12.5 to 13.5 pounds
depends on the size, professionals play with a size 5, circumference of 27-28 inches
the size of official size of football....that is size 5...has to be around 27-28 inches in circumference..... the weight has to be around 14-16 oz
60 yards in a game , but he thinks he can throw about 70-80yrds
The 2011 Laws of the game document states: Unless otherwise determined by the AFL, a football shall be of a symmetrical oval shape and conform to the standard size of 720-730 millimetres in circumference and 545-555 millimetres transverse circumference and be inflated to a pressure of 62-76Kpa.
