What is the required piece of information tho find the area of a circle?
The only piece of information required to find the area of a circle is the radius of the circle. Once you know the radius of the circle, the area is simply the radius squared multiplied by pi (approximately 3.14).
How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
Does a diameter go all the way across or halfway across a circle?
A diameter goes all the way across a circle through the center. A radius goes half way across, from the center to any point on the circle. So a circle's diameter is two times its radius.All the way through the centre of the circle but the radius only goes half way from the centre of the circle
