Find the area of the sector determined by the given radius $r$ and central angle $\theta .$ Express the answer both in terms of $\pi$ and as a decimal approximation rounded to two decimal places. (a) $r=4 \mathrm{cm} ; \theta=\pi / 10$ (b) $r=16 \mathrm{m} ; \theta=5^{\circ}$ (c) $r=21 \mathrm{ft}: \theta=11 \pi / 6$ (d) $r=4.2$ in.; $\theta=170^{\circ}$

00:02 So i have a sector of a circle, and the circle has a diameter of 18 feet, and it has an angle of 3 pi over 2 radians.
00:21 And i want to find the area of the sector.
00:29 So the formula for area of a sector is 1 half r squared theta, and theta must be in radians.
00:42 R is the radius.
00:46 So if the diameter is 18 feet, i know r is half of 18, or 9 feet...
