Answer: A
Step-by-step explanation:
The diameter is 10 ft and to get r you divide 10 by 2 to get 5. Then square the radius and multiply by h.
Since it is isosceles right triangle, both legs = 5 inches.
using pythagoras theorem,
hypotenuse^2 = 5^2 +5^2 = 25+25 = 50
taking square root on both sides,
hypotenuse = sqrt 50 = 5 sqrt 2 or 7.071
rounded to nearest tenth,
length of hypotenuse is 7.1 inches.
