Question

The semi major axis of an ellipse is 100mm long and distence between its foci is 70mm draw the ellipse

Answer 1

MajorAxis = widest axis diameter of ellipsis

MinorAxis = smallest axis diameter of ellipsis

f=√(jpow2−npow2)

f is the distance from each focus to the center

j is the semi-major axis (major radius)

n is the semi-minor axis (minor radius)

60^2 + f^2 = 10^2

3600 + f^2 = 10000

f^2 = 6400

f = 80
