Answer:
vertex - (0,0)
focus - (0, 3/4)
directrix - 3/4
parabola- x^2=-3y
graph of equation:
First, we find the area of the circle.
A = pi * r^2
A = pi * (1 cm)^2
A = pi cm^2
The area of the circle is pi cm^2.
The area of the triangle is also pi cm^2.
Now we use the area of a triangle.
A = (1/2)bh
(1/2)bh = A
(1/2)(3 cm)h = pi cm^2
(3 cm)h = 2pi cm^2
h = (2/3)pi cm
The exact height is
If you want an approximate height, then it is 2.09 cm.
