radius = diameter ÷ 2
area = π x radius2
= π x (diameter ÷ 2)2
= π x (10 cm ÷ 2)2
= 25π cm2

What is the formula for finding diameter when given the area?
Assuming you mean a circle, use the formula for the area of a circle, which is usually expressed in terms of the radius, and solve for the radius. Then you can multiply that by two to get the diameter, since the diameter is twice the radius.
What is the area formula of a circle with a diemeter?
The area of a circle is πr^2 where r is the radius and in terms of diameter it is πD where D is your diameter.
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 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 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 circle in terms of pie with a diameter of 36?
The area of a circle, in terms of pie, with a diameter of 36 is: about 324pi
If the diameter of a circle is 40 m then what is the area in terms of pi?
If the diameter of a circle is 40 m then the area (in terms of Pi) is: about 400pi m2
What is the formula for finding diameter when given the area?

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 formula of a circle with a diemeter?
The area of a circle is πr^2 where r is the radius and in terms of diameter it is πD where D is your diameter.
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.
How do you find the diameter of a circle in the terms of pi?
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
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]
