First we need to find the radius of the cylindrical tree trunk if the circumference C=4 feet: C=2rπ, r=4/(2π)=2/π. Now we find the volume V: V=r^2π*h, where h=20 feet is the height. So we input the numbers: V=(2/π)^2*π*20=(4/π²)*π*20. π in the nominator and the denominator cancel out: V=(4/π)*40=80/π. The volume of the cylindrical tree trunk is V=80/π feet^3
(f+g)(x) = f(x) + g(x)
(f+g)(x) = 3x-2 + 2x+1
(f+g)(x) = (3x+2x) + (-2+1)
(f+g)(x) = 5x - 1
Answer:
V = 127.5in^3
Step-by-step explanation:
The volume of a rectangular prism is:
Volume = length x width x height
Therefore, in this equation it would look like this:
Volume = (5) x (5) x (5.1)
Volume = 127.5in^3
The volume of the computer is 127.5in^3.
