If you have four quarters, three dimes, two nickels, and two pennies, what fraction of the whole coin collection is in dimes? how is it 3/11

4 quarters + 3 dimes + 2 nickels + 2 pennies = 11 coins total

We are interested in finding out how much of the collection is dimes only --> 3 dimes / 11 total = 3/11.

Hope This Helps!      Have A Nice Day!!

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
