Pleas me find the area of the shaded sector

ANSWER

461.7 yd²

EXPLANATION

The shaded region represents a sector.

The area of the sector is a fraction of the area of the whole circle.

Area of sector

We substitute the angle of the sector and the radius of the circle to obtain:

Therefore the area of the shaded region to the nearest tenth is 461.7 square yards.

Area of shaded sector = 461.5 yd²

Step-by-step explanation:

Points to remember

Area of circle = πr²

Where 'r' is the radius of circle

To find the area of given circle

Here r = 17.8 yd

Area = πr²

 = 3.14 * 17.8²

 = 3.14 * 316.84

 = 994.8776 yd²

To find the area of shaded region

Central angle of sector = 167°

Area of sector = (167/360) * area of circle

 =  (167/360) *994.8776

 = 461.52 ≈ 461.5 yd²

State if the triangles in each pair are similar. If so, state how you know they are similar

A. Similar by the sss rule
