Find the area A of the sector of a circle of radius 90 in formed by central angle 1/6 radian.
miv72 [106K]

Answer:

2121 in^{2} Rounded to the nearest inch.

Step-by-step explanation:

A = \pi r^{2}  Is the formula for a circle, but we only have a portion of a circle so we will have to adjust the formula for a part of the circle.

A = \frac{\frac{\pi }{6} }{2\pi } \pi r^{2}  The \frac{\pi }{6} is the part of the circle and the whole circle is 2\pi

\frac{\frac{\pi }{6} }{2\pi } is the same as \frac{\pi }{6}÷\frac{2\pi }{1} Which is the same as \frac{\pi }{6} x \frac{1}{2\pi } Which is the same a \frac{1}{12}

A = \frac{1}{12}\pi90^{2}

A = \frac{1}{12}(3.14)(90)(90) = 2119.5.  When you use the \pi on your calculator you get a slightly different number.  This is due to rounding.

A = 2120.575041
