Circumferencec is defined by 2pi*r, where r is the radius. Therefore, we can do the equation:

C=2*pi*30
C=60*pi
Normally, you would multilply your number and pi but since we're told to leave it in terms of pi, the answer is 60.

Ms. Kincaid keeps a supply of dimes and quarters in her car to pay for highway tolls. A week’s supply of toll coins contains 5 m
Alecsey [184]

Answer: (A) 10

<u>Step-by-step explanation:</u>

                <u>Value</u>       <u>Quantity</u>     =  <u>TOTAL Value</u>

dimes:        .10            Q + 5        =    .10(Q = 5)

quarters:    .25               Q           =      .25Q


Dimes + Quarters = $4.00

.10(Q + 5) + .25Q = 4.00

.10Q + .50 + .25Q = 4.00

           .50 + .35Q = 4.00

                    .35Q = 3.50

                          Q = 10

Quarters = 10

Dimes = Q + 5

           = 10 + 5

           = 15
