The area of the ellipse with half-axes 35 and 35 equal to 3848.338
Method for calculating the area of an ellipse:
Through the half-axes
Half-axis length a:
Half-axis length b:
An ellipse is a closed flat curve
Ellipse area formula
where a,b are semi-axes
Solution:
S = π·a·b
=π·35·35
=
3848.338
a: The area of the ellipse with half-axes 35 and 35 equal to 3848.338
