In this question, we are going to use slices to calculate both the circumference AND the area of this shape. {a} {4 points] By dividing the ellipse into four equal parts, use the arc length formula to compute the circumference of the ellipse. (Hint: You may wish to use trig substitutions] (b) (4 points) Now, let us try our hand at computing the area. First make a horizontal slice as shown Write down the area ofthis slice. {c} [2 points} Using your horizontal slices in part (b). compute now the area of the ellipse. (Hint: Vou may wish to use trig substitutions}
