See a doctor....It could be Lyme Disease.
The circumference of a circle is the length of the circle's perimeter.
Yea painful death
Already out
A vehicle about to enter a roundabout has no right-of-way over vehicles already in the circle Arkansas
There is no such thing as a "square circle". If you mean "8 square feet", that is already the area.
of corse
You already know the radius.
The Secret Circle has already started in the UK. You can watch it on Sky Living on Wednesdays at 8:00PM
Well, if you know the diameter of the circle already, then you can divide it by half to get the radius. If you don't have the diameter however, then you simply have to find the middle of the circle and measure from the middle of the circle to the edge. That would be your radius.
you take the degree that you already have and subtract it from 360 and if you don't already have a degree try to weasel it out of your teacher
That depends what you mean with "a 20 cm. circle". If 20 cm. is the radius, you already have the answer. If 20 cm. is the diameter, the radius is half the diameter. (10cm)
The area of a circle is pi * radius2. If you already have the radius squared, you just have to multiply that by pi.
