Question

Proof of areas (using calculus).

Answer 1

Show the Area of triangle A,C,B = 3/4 area under the parabola

Answer 2

@zepdrix I need hewlp.

Answer 3

Woops! I made a mistake in the picture, I think.
the (a+b)/2 is not that entire area, only one point on that line between points a and b

Answer 4

Ew. XD You use the (1/2)(B)(H) & pi*r/2

Answer 5

how do I go about doing that haha it's confusing without numbers D:

Answer 6

You already got the numbers for the parabola =3/4 right?
So remember that the diameter of a circle will be equal to the height (or longer side of the triangle)

Answer 7

mm well..I have that the area of the triangle = 3/4 of the entire area under the semi circle (if it is a semi circle)
