Changing a Circle to an Oval

This calculator converts the area of a circle into an oval area of the same size

Circle Formula's

Radius
R = D ÷ 2
where R = radius, D = diameter

Area;
A = π * D² ÷ 4
where A = area, π = 3.14159..., D = diameter

Circumference;
C = 2 * π * D ÷ 2
where C = circumference, π = 3.14159...., D = diameter

Oval Formula's

Area
A = π * la * sa ; ÷ 4

Long Axis
La = (A / (π * (Sa ÷ 2)) * 2
where La = long axis, A = area, π = 3.14159...., Sa = short axis

Perimeter
S = Sa ÷ 2 , L = La ÷ 2
Pa = (S + L) * 3
Pb = ((3 * L + S) * (L + 3 * S))²
P = π * (Pa - Pb)

where P = perimeter, La = long axis, π = 3.14159...., Sa = short axis

Circle to Oval

Select unit:
diameter of the circle {{selectedunit.m1}}
short axis of oval {{selectedunit.m1}}
decimal rounding # of digits in results

Results:

circle's radius {{selectedunit.m1}}
area of the circle {{selectedunit.m1}}²
circumference of the circle {{selectedunit.m1}}
long axis of the oval {{selectedunit.m1}}
perimeter of the the oval {{selectedunit.m1}}

Calculation

  1. enter the diameter of a circle
  2. the length of the short axis of the oval
  3. number of decimal places required in results

Results

  1. radius of the circle
  2. the area of the circle
  3. the perimeter of the circle (circumference)
  4. the long axis length of the oval
  5. perimeter of the oval
