Answer 1

= 400pi + 144pi + 256pi
= 800pi
= 2513.27 cm sq. approximately

Answer 2

The answer is 100pi+96

Answer 3

(100*3.14)+96 should be your answer.

Answer 4

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

Answer 5

So 410 cm sq approx :)

Answer 6

oppss the first should all semi circles, i mean :)

Answer 7

First use Pythagoras theorem to find the hypotenuse of the triangle.. That was you'll find out the radius of the semicircle :)

Answer 8

oh, thanks guys :)
