An ellipse has an area of 4.71 in.2 and a minor axis that is 2.00 in. long. Solve for the major axis, and then sketch the ellipse using that dimension. Show only those dimensions needed for the area calculation. Note: Each grid unit = 0.25 inch.
Accepted Solution
A:
by definition we have that the area of the ellipse is A = pi * a * b where a: Semi-main axis b: Semi-minor axis Substituting and clearing: a = A / (pi * b) = (4.71) / (PI * 1) = 1.50 in. Therefore the main axis is 2 * a = 2 * (1.50) = 3in Graphic attached.
