Can someone help find the circumference and area of this??? ​

Step-by-step explanation:

area formula is

π

plug in values:

9π

which equals

28.2743339

or you can write 9π im not sure what your teacher prefers

circumference formula is

2πr

which equals

6π

or

18.8495559

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
