We don't know what the "width" of a circle is.

The diameter of a circle is all the information you need to calculate the area.

-- Take 1/2 of the diameter. Call is "R"". (That's called the circle's "radius".)

-- Area of the circle is: (pi) x (R2) .

"pi" is a number that can never be written down exactly. If you need to calculate

an area, you can use 3.14 for 'pi', or you can use 22/7 . They're both very close.

How do you find the area of a circle when the radius is unknown?

By using the other information supplied about the circle to calculate either its radius (from which its area can be calculated) or its area (if the circle is similar to another with a given area and some ratio between the two circle is given):If the diameter is given: radius = diameter ÷ 2If the circumference is given: radius = circumference ÷ 2πIf the circle is similar to another circle which has a given area, and the length ratio is given; square the length ratio to get the area ratio and apply to the given area.
