Bye dividing one third and multiplying by pi
Since it is a right triangle, we can apply the Pythagorean theorem.
The square of the hypotenuse is equal to the sum of the squares of the sides.
We'll call H the hypotenuse and L to the side.
H² = L² + L² = 2L²
H² = 2x11²
ANSWER = F) =


---------------------------------------------------------
Take away 1 from both sides
---------------------------------------------------------

---------------------------------------------------------
Evaluate the value on the right
---------------------------------------------------------

----------------------------------------------------------
Multiply by 15 on both side
---------------------------------------------------------

---------------------------------------------------------
Evaluate
---------------------------------------------------------

---------------------------------------------------------
Divide by 6 on both sides
---------------------------------------------------------

---------------------------------------------------------
Simplify
