You use the formula A=(pi)r^2 solve for r which will give you the square root of A/pi. In your case the area has pi already in it so it is just 2 times the square root of 8.

Square foot of a circle?
To find the area of a circle, either the diameter or the circumference must be known. The formula for the area from the diameter is (pi)*(1/2 of diameter) squared. From the circumference, simply substitute (circumference / pi) for diameter.
Find the area of a circle with a diameter of 5 inches long?
pi x 2.5 squared because 2.5 is the radius. the radius OS half the diameter. the formula for area of a circle is pi x r squared. pi is 3.141593
How do you figure out the diameter of area of a cricle?
To find the area of a circle, you multiply the radius by itself [squared] and then you multiply their product by pi. To find the diameter of circle, you can a)Multiply the radius by two b) Divide the area by pi, find the square root of that product and then multiply it by two.
What is the formula to find the are of a circle with diameter?
A(Circle)=Pi*Diameter^2 ^2 = squared or to the 2nd power
How do you find the area and perimeter of circle?
First you have to measure the diameter of the circle. The diameter is pi (pi is approximately 3.1415) times the diameter is the perimeter. Half the diameter is the radius and the area of a circle is pi times the radius squared. So for example, let us say that you have a circle with a diameter of 3 inches. The perimeter is then about 9.42 inches, and the area is about 7.07 square inches.
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
Find the area of a circle?
diameter squared times pi
How do i find circumference and area of a circle?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
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 the circumference and area of a circle that has a radius of 4?
To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.
How do you find the diameter if you have the area of a circle?
Since the area of a circle is (Pi)times(Radius squared) then you would reverse the process to find the radius, and hence, the diameter. Divide the area by Pi (3.14159...) and you would have the radius squared. Take the square root of that and you have the radius. To get the diameter, multiply the radius by 2.
How do you find a area with the diameter of a circle?
Area = Pi(radius)squared. You only need the radius of a circle to find the area. To find the radius, when you have the diameter, divide the diameter by 2, because the diameter forms two radii. After you have found the radius, plug in the radius into the area equation: Area = Pi(radius)squared In other words, you can say the other equation for the area of a circle is: Area = Pi(1/2Diameter)squared

To find the area of a circle, either the diameter or the circumference must be known. The formula for the area from the diameter is (pi)*(1/2 of diameter) squared. From the circumference, simply substitute (circumference / pi) for diameter.
Find the area of a circle by measuring its diameter?
Area = Pi * (radius squared), and radius = 1/2 diameter, so A = Pi*(0.5d)^2
Find the area of a circle with a diameter of 5 inches long?
pi x 2.5 squared because 2.5 is the radius. the radius OS half the diameter. the formula for area of a circle is pi x r squared. pi is 3.141593
What is the formula to find the area of a circle with with a diameter?
if you are given a diameter divide it by two to get the radius! From then on, it is just simple Pi R Squared
What is the formula to find the are of a circle with diameter?
A(Circle)=Pi*Diameter^2 ^2 = squared or to the 2nd power
