How man square inches in a 4 round circle?
If the circumference of the circle is 4 inches then the radius = 4/(2*pi) = 0.6366197724 inches And the area of the circle = pi*0.63661977242 = 1.273239545 or about 1.273 square inches
What is the diameter of circle if circumference is 240cm?
Oh, dude, so like, the formula for circumference is 2πr, right? And if the circumference is 240cm, you just divide that by 2π to get the radius. Then, double the radius to get the diameter. It's like, basic math, man. So, the diameter would be 76.3cm.
What is circumference of the universe?
There are many things man can not prove. This is one of them.
What does pack man look like?

How do you find the length of arc BC when the central angle of ab is 120 and the radius is 10?
This is your lucky day ! Watch now, as the Great and Powerful WA Contributorsolves your problem and answers your question without ever seeing the drawingthat's supposed to go along with it, and with no idea what 'BC' and 'ab' are . . .-- A whole circle has a central angle of 360 degrees.-- A whole circle with a radius of 10 has a circumference of [ (2 pi) x (radius) ] = 20 pi .-- A slice of cake with a central angle of 120 degrees is 1/3 of a circle.-- The arc at the fat end of the slice is 1/3 of the full circle's circumference = 20 pi/3 = 20.944 (rounded)-- Just in case 'BC' is the long arc, then its length is the other 2/3 of the whole circle= 2 x 20 pi/3 = 41.888 (rounded)Pay no attention to that old man behind the curtain.
