The number of half dollars coins are 5 and the number of the quarters dollars coins are 12.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
You have a cup with 17 coins inside.
The total inside the cup is $5.50.
Let x be the number of half dollars and y be the number of the quarters dollars.
Then the equations will be
x + y = 17 ............1
0.5x + 0.25y = 5.5 ...........2
By solving equations 1 and 2, we have
x = 5 and y = 12

Answer:
The area of the circle is 50.24 m.
First find the radius which is half the diameter. So our radius is 4.
A =3.14 * 4^2
A= 3.14 * 16
A = 50.24
So your answer would be A.
I hope I helped!
