We have a right angled triangle with base 60 and hypotenuse 61
so opposite side = sqrt (61^2 - 60^2) = sqrt121 = 11 feet
so the wire should be 24 feet high on one pole and 35 feet high on the other.
Its the last choice
16x^2 - 8x + 1 = (4x - 1)^2
Answer:

Step-by-step explanation:
A diameter is two times longer than a radius. Therefore, if the diameter
d = 24in, then the radius r = (24in) : 2 = 12in.
The formula of an area of a circle:

Substitute:


Then
