The area of a circle is

The radius is half the diameter, so we have

After I read the equation, I remembered that anything to the power of 1 is itself. so f(x)=2-9
2-9= -7
therefore, f(x)= -7
if x=1, then the f(x) must be Y
<u><em>therefore, your answer should be y= -7</em></u>
Answer:
A
Step-by-step explanation:
Area of a base: 16 × 15 ÷ 2 = 120
Area of sides:
37 × 15 = 555
37 × 16 = 592
37 × 20 = 740
Area of prism: 2 × 120 + 555 + 592 + 740 = 2127
That would just be 5 inches
