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.
An ellipse always has two axes of reflection; an oval has one or more.So, an egg-shape is an oval, but not an ellipse.In short an ellipse is an oval, but an oval may or may not be an ellipse.
A three-dimensional oval is commonly referred to as an "ellipsoid." An ellipsoid is a surface that is generated by rotating an ellipse about one of its principal axes. Depending on the lengths of its axes, it can take various forms, such as a spheroid, which is a special case of an ellipsoid where two of the axes are equal.
An oval has two perpendicular axes, one longer and one shorter. In other words, an oval has a maximum length and a minimum length. You can measure both.
If you are at the centre of the major and minor axes of an oval, to roate one complete turn to arrive back where you started is 360 degrees. or 2pi radians.
pi*a*b where a and b are the lengths of the semi-major and semi-minor axes.
the formula for calculating the surface area of an oval is A = Pi * a * b where a & b are the semimajor(half the long) and semiminor(half the short) axes
A = Pi * a * b where a & b are the semimajor(half the long) and semiminor(half the short) axes
Rotational symmetry counts how many times a shape will fit onto itself when it is rotated 360°. When an oval (I assume you mean an ellipse) is rotated it will fit onto itself after 180°, thus it has rotational symmetry (of order 2).
To find the linear feet around an oval, you would typically calculate the circumference. The formula for the circumference of an oval is (a + b)π, where a and b are the semimajor and semiminor axes of the oval. In this case, for a 33x18 foot oval, the semimajor axis (a) would be 33/2 = 16.5 feet and the semiminor axis (b) would be 18/2 = 9 feet. Therefore, the circumference would be (16.5 + 9)π = 25.5π feet. This is approximately 80.07 feet.
