Eugene knows the circumference of a circle is 125.6 meters. Does he have enough information to find the area? Yes, because he could divide by 3.14 to find the diameter and then divide that result by 2 to find the radius. Once he has the radius, he can use the formula. Yes, because the area will just be twice the circumference so all he has to do is multiply by 2. No, because the circumference equals C = (Diameter) times pi and there is no Pi in 125.6. No, because the circumference equals C = (Diameter) times pi so he could only find the diameter. He needs the radius for the area formula.

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

answer:

c) the x-coordinate of the center of the circle increases by 3
