It would be to little because it would only be 30 cents
pi·(7.2/2)^2·x = 2·pi·(7.2/2)^2 + 2·pi·(7.2/2)·x
x = 4.5 = 4 1/2
O = V = 1458/25·pi = 58.32·pi
(-2x+4)+2(2x+1)= -2(-x-3)
So with this, you can rewrite the equation as: 
Firstly, solve the multiplication: 
Next, combine like terms, and <u>your answer will be:
</u>
Its a we know its this cause its rational and if its a rational number it is also an integer and a whole number
