In Reply to: Mr G. ... Why h = sqrt(15.275) isa special case???.. I don't get it ...(n/t) posted by Subhotosh Khan on September 17, 2002 at 11:33:19:

: : Did you ever consider that h might just equal the square root of 15.275?

: : : : I have a question. There is a semi-circle with a rectangle in it. The radius of the semi-circle is 10. I am supposed to find a function that models the area A of the rectangle in terms of its height h. The answer is A(h) = 2h(square root 100-h squared) when 0: : : : Can you help?!

: : : Draw a good picture. Draw the half circle then draw a rectangle inside
: : : of it as you have described. Next draw in a radius line from the
: : : center of the circle to one of the far corners of the rectangle. Now
: : : draw a line straight up from the center of the circle to the edge of
: : : the rectangle. Identify all the right triangles you can find. Label all
: : : the lengths you can. If you do this carefully you should be very close
: : : to the full answer.
