Okay so you know that the area is equal to 7.
So:
A=7
the area for a circle is A= (pi)r2
where A is the area.
so 7=(pi)r2
solve for r
7/(pi)=r2
sqrt (7/(pi))=r
rationalize it [sqrt(7pi)]/(pi)
if you double the radius you get the diameter.
2r=d
d=2[sqrt(7pi)]/(pi)

What is the area of a circle with a diameter of 14 centimeters?
Area can be expressed by the formula A=(Pi)r2, where A is the area and r is the radius.To find the radius of the circle, divide the diameter by 2.14 cm/2 = 7 cmA = (3.14159)(72)= 153.938 cm2Therefore, the area of a circle with a diameter of 14 cm is approximately 153.9 cm2.
How do you find the diameter of a circle when you know the area?
Divide the area by pi. (3.14 or 22/7) Find the square root of your answer. This will be the radius. Multiply the raduis by 2.

What is the area of a circle when the diameter is 7 mm?
Well, honey, if the diameter of a circle is 7 mm, then the radius is half of that, which is 3.5 mm. The formula for the area of a circle is πr^2, so plug in 3.5 for the radius and you get an area of approximately 38.48 square millimeters. So there you have it, darling!
What is the area of a circle with a 5 meter diameter?
diameter= 5m radius= diameter/2 = 5/2 =2.5m area of the circle= πr*r =22/7*2.5*2.5 =19.64....m
