Question

In circle P with m NPQ = 46 and NP=20 units find area of sector NPQ.

Answer 1

Answer:

160.57

Step-by-step explanation:

The formula is:

$angle/360 *\pi *radius^2$

Because you find the total area of the circle, but the sector only represents NPQ/360 so you have to multiply the area with that.

$46/360 * \pi *20^2$ = $23/180 * \pi *400$

= $160.57029...$

Rounded to the nearest hundredth this would be 160.57

Answer 2

Answer:

Round to the nearest hundredth.
