Answer:
b = 21
Step-by-step explanation:
By the Pythagorean Theorem, which states that if you have a right angle with legs of a and b, and a hypotenuse of c, then a^2+b^2=c^2. Use this on the right triangle in the diagram to get 841 = 400 + b^2, or 441 = b^2 and b = 21.
Note: I think that the 1st diagram was unnecessary. ;)
The equation factors as
.. (x +3)(x +4) = 0
By the zero-product rule, the roots are
.. x1 = -4
.. x2 = -3
Area of circle=(pi)r^2
=(pi)(225ft)(225ft)
=159,043.1281
then find 40% of surface area: 159043.1281 x 40%=63,617.25124
Hope that is helpful!
