5 0

Answer:

197.77

Step-by-step explanation:

Area of circle: A=pi r^2

A= pi 9^2

A= 81 pi

only half of the circle so 40.5

Area of a Square: L x W

18 x 18 = 324

324 - 40.5pi = 197.77

State whether the triangles are similar. If so, write a similarity statement and the postulate or theorem you used. The diagram
olga55 [171]

Givn : OK = 3, OJ = 30, KN = 1, JM = 3

ON=OK+KN=3+1=4

OM=OJ+JM=30+10=40

In triangles OKJ & ONM,

OKOJ=330=110

ONOM=440=110

Angle O is common in both the triangles.

Two sides are in same proportion and the included angle is common (SAS) . Hence both the triangles are similar.

That means KJNM=110 or the two sides are parallel.

Hence ˆK=ˆN,ˆJ=ˆM corresponding angles.
