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
What is the area of a quarter of a circle that has a length of 4.5cm and the width of 4.5cm?
What a strange question. A circle does not have a length or a width. It has a diameter and that all.
If the area of a circle is given as 67cm squared find the diameter and then circumference of this circle?
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
What is the area of a circle that has a 10 inch diameter?
The area of a circle is A = pi times diameter² / 4. Given diameter d = 10 inches. Area A = 78.5398 inches².
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.
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.
What is the width of a semicircle with an area of 180ft squared?
The diameter of the circle is 21.4 feet, approx.
How do you find area of a circle when diameter is given?
TTr2 [Pi r squared] finds the area of the circle. TT x d [Pi x diameter] finds the circumference of a circle]
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
What is the area of the park if diameter of circular park is 14meter and width is 3.5meter?
The answer depends on whether the width is inside the 14 metre circle or outside.
How do you find the area of a circle when given diameter?
A = pi x d2 / 4
