Side AB of triangle ABC lies on the diameter of circle O as shown in the figure above. Half of the height to side AB equals 4/5 of the radius of the circle.
If the area of triangle ABC is 90, what is the closest approximation to the area of semicircle AOB?
35
45
88
180
350
I didn't understand the question. What does the bolder part mean ?
Though I solved it like this:
Approximating area of part of the triangle inside the circle as (90/2), I chose the answer as 88
