The formula to find the volume of a cylinder is pi mulitplied by radius squared multiplied by height. You multiply 3.14×4 squared×9 which is 452.16 or 452. The answer is 452 inches cubed.
Answer:
Step-by-step explanation:
Instead of plugging in and right away, notice that
and now evaluating this expression at the two given values is easier, if only a little:
Basically (g of f)x=(f(g(x)) so
g of f=f(g(x))=7(5x^2+4x-3)+5
distribute
f(g(x))=35x^2+28x-21+5=35x^2+28x-16
g of f=35x^2+28x-16
28 all you have to do to find the area of a triangle is multiply using l x w and divide in half.
