One coin is randomly selected from a jar containing 70 nickels, 100 dimes, 80 quarters and 50 one-dollar coins. what is the probability of selecting a coin with a value greater than $0.10?

Add all the coins together for the total coins:

70 + 100 + 80 + 50 = 300 total coins.

The only coins greater than 0.10 are the quarters and one-dollar coins.

Total of those two coins: 80 + 50 = 130 coins.

Probability of picking one of those = 130 / 300, which reduces to 13/30

< 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

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
