= 400pi + 144pi + 256pi = 800pi = 2513.27 cm sq. approximately
The answer is 100pi+96
(100*3.14)+96 should be your answer.
the area of all triagles : = 1/2 pi (10^2 + 8^2 + 6^2) = 1/2 pi (10^2 + 10^2) = 1/2 pi 200 = 100 pi area of triangle = 1/2 * 12 * 16 = 96 total = 100pi + 96
So 410 cm sq approx :)
oppss the first should all semi circles, i mean :)
First use Pythagoras theorem to find the hypotenuse of the triangle.. That was you'll find out the radius of the semicircle :)
oh, thanks guys :)
