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 semi-circle if you know the diameter?
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
What is the width of a semicircle with an area of 180ft squared?
The diameter of the circle is 21.4 feet, approx.
What is diameter in geometry?
diameter refers to the area across a circle through its center. it is the longest chord possible for any given circle.
How do you find the area if given the circumference of a circle?
Times length times width
How do you find the area of a circle if the diameter is given?
multiple the diameter by 2 to get the radius, then use your equation and go from there
