central angle of a sector is 72° and the sector has an area of 16.2(pie) ft^2. what is the radius of the circle?
Cloud [144]
Sector area = (central angle / 360) * PI * radius^2
sector area = (72 / 360) * PI * radius^2
radius^2 = sector area / [(72 / 360) * PI]
radius^2 = 16.2 * PI / [(1 / 5) * PI]
radius^2 = 16.2 / .2
radius^2 = 81
radius = 9

PLEASE HELP
Savatey [412]
Correct Answer: Option A

The next step in simplification will be to convert the squared term so that it no longer contains a square.

So, we are to simplify the term cos^{2}(2x)

Using the half-angle identity we can write:

cos^{2}(2x)= \frac{1+cos(4x)}{2}

Using this value, the equation becomes:

sin^{4}x=1-2cos(2x)+ \frac{ \frac{1+cos(4x)}{2} }{4}

Therefore, option A is the correct answer.
