## Steps to Find Area & Circumference of a Ellipse

The step by step workout for how to find what is the area and circumference of a ellipse.__Workout :__

step1 Address the formula, input parameters and values

Majaor Axis a = 5 in

Minor Axis b = 10 in

Area of Ellipse A = πab

Circumference P = 2π√a² + b²/2

step 2 Apply the values in area formula

Area = π x 5 x 10 in²

= 3.14159265 x 5 x 10 in²

Area = 157.0796 in²

step 3 Apply a and b values in cicumference formula

Circumference P = 2π√(5² + 10²) in²/2

= 2π√ (25 + 100) in²/2

= 2π√ (125) in²/2

= 2 x π x √(62.5) in²

= 2 x 3.14159265 x 7.9057 in

Cicumference = 49.6729 in

## Definition & Formulas

**Ellipse** is a two dimensional plane or geometric shape represents a regular oval shape. A surface of unparalleled axis (not vertical) cross section of cylinder is also an ellipse shape.
