A tough question, with no exact answer.
Call half the longest distance across the oval (x) and half the shortest distance across (y). These are called the semi-major and semi-minor axis.
The area is simple enough. (pi)(x)(y)
Figuring the circumference is a bear of a calculus problem, but you can get close enough.
A good approximation is to take 2(pi)((x²+y²)/2)(1/2). That is an ugly expression, so read it: Two pi times the square root of "x²+y² over 2" ■

How do you find the circumference of a circle when you know the area?
OK, SO to find the area of a circle, you find the radius (half of the diameter), and fit it into the equation πr2=A where r equals radius and A = area. The perimeter of a circle is π multiplied by the diameter. π is ≈ 3.1415296.
If the area of a circle is 201.06 then the circumference of the circle is?
The circumference would be 50.265
How many acres is in an area with a circumference of 87 miles?
The area of a circle with a circumference of 87 miles is: 385,472 acres.
What is the area of a circle with a circumference of 50pi?
To find the area of a circle, the formula is pi*r2, and the circumference is 2pi*r Now plug in the information given. Circumference is 50pi. 50pi = 2pi*r Divide both sides by pi. 50=2*r Divide both sides by 2. 25 = r The radius equals 25. Now to find the area, using pi*r2. We know the radius is 25. pi*(25)2 Find the square of 25. pi*625 The area of the circle is 625pi square units (about 1963.5 square units)
What is the area of a circle with circumference 9.42?
The circumference of a circle of 7 inches is: about 21.99 inches. You can easily do this calculation for other circles by multiplying the diameter by Pi (about 3.1416).
How do you find the area of a cirle with the circumference?
Area = circumference squared... You do circumference divided by 4,... and then divide that by Pi.
How do you calculate the circumference of an oval?
If it is an elliptic oval, the circumference can be calculated by πab, where a and b are the lengths of the minor and major axes.
How do you find the height of a cylinder if you have the circumference and the surface area?
you divide the surface area by the circumference.
Find the circumference of a circle with an area of 82?
The circumference is: 32.1
Circumference of 35 acres?
The shape (circular, oval, rectangular, irregular, etc.) must be given as well as the area.
How do you find the area of a circle knowing only the circumference?
To find the area of a circle knowing only the circumference, you can use the formula A = (C^2) / (4π), where A is the area and C is the circumference. Square the circumference, then divide it by 4π to get the area.
How do you find the circumference of a circle with the area given?
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
