First you times 3.14 by the diameter and there you go
If you do the actual multiplications, you will find out soon.
The answers depend on what you want to "do" and what information you have.
They are its circumferences
If you are given the radius (r) or diameter (d, which is twice the length of the radius) the equation to find the circumference (C) is: C=d(pi) or C=2r(pi).
Multiply each of the diameters by pi (pi = 3.14159265 or 3.14 for rough approximation) to find the circumferences of the circles.
80ft
The perimeter of a circle
An arc
They are circumferences
Just do the multiplication.
10ft 3in * 10ft 3 in = 10.25 ft*10.25 ft = 105.0625 sq ft.10ft 3in * 10ft 3 in = 10.25 ft*10.25 ft = 105.0625 sq ft.10ft 3in * 10ft 3 in = 10.25 ft*10.25 ft = 105.0625 sq ft.10ft 3in * 10ft 3 in = 10.25 ft*10.25 ft = 105.0625 sq ft.
10ft. By 10ft.-100 square feet
10ft by 10ft shockingly
easy, just divide 2*pi*r by pi*r-squared. You get 2/r .
it is 10ft tall.
The diagonal is 14.142 feet.
