If a circle has a radius of 9 and a sector defined by a 254 degree arc, what is the area of the sector

1 answer:

8 0

The answer is 179.451 or 1143π/20.

The arc is 254°. A circle is 360°. This means the arc makes up 254/360 of the circle. We will multiply this fraction by the area of the circle, which is

A = πr² = π(9)² = 81π = 254.34

81π(254/360) = 20574π/360 = 1143π/20 = 179.451

Step-by-step explanation:

In order to calculate the time that Charlotte took we just first have to calculate the time that Terrence took to finish the word search, that is done by multiplying the 32 minutes that Frank took by the three quartes that it took terrence:

$Time=(\frac{3}{4}) (32)\\Time=(\frac{96}{4})\\Time=24$
