Someone help me
Aneli [31]

Answer:

see the explanation

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=\pi D

where

D is the diameter

In this problem we have

C=2.88\ in

\pi=3

substitute and solve for D

2.88=(3)D

D=2.88/3

D=0.96\ in

we know that

The length of the row of quarters is equal to multiply the diameter of the quarter by the number of quarters in the row

so

For 4 quarters in the row, the length is equal to --> 0.96(3)=3.84\ in

For 6 quarters in the row, the length is equal to --> 0.96(6)=5.76\ in

For 12 quarters in the row, the length is equal to -> 0.96(12)=11.52\ in
