8
What is the area of a circle with a diamiter of 46?
The area of a cirle is: PI * r2 Where "r" is the radius, and PI is approximately 3.14. Hint: A radius is half of the diameter.
Area of a cirle with a circumference 66cm?

Which figure is not a solid a cone a cube a sphere a cirle?
cube
The radius of a cirle is what percent of the diameter?
the radius of a cirle is what percent of the diameter
What is the circunference of a cirle with 12 diameter?
circumference = pi*diameter
Is the radius of a cirle half of the diameter?
Yes.
If you have a diameter of 8 what is the radius?
Four - Diameter is the length of the circle, one end to the other through the cirle, while radiusis from the middle of the circle , out. Hence Being half. s :)
What is the diameter of a cirle that the area is 28 square inches?
5.9723 inch
How does pi relate to the circumference and diameter of a cirle?
The cicumference of any circle divided by its diameter is aways equal to pi.
What is the circumference of a cirle with a diameter of 16?
16 pi = almost exactly 50¼
What is the formula for the circumference of the cirle?
circumference of a circle = 2*pi*radius or pi*diameter
What is a area of a circle?
You must find the circumference. First measure a line through the cirle. Then that is the diameter then multiply the diameter by 3.14 then you have the area! Hope that helped!

What is the area of a cirle if diameter is 16?
Area of a circle is pi r^2 diameter is twice the radius. 3.14*8*8=64*pi or approximately 200.96
Work out the perimeter of the semi-cirle when diameter is 15cm?
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
