The circumference of a redwood tree trunk is 20π ft, and it is 100 ft tall. what is the approximate volume of the redwood tree trunk? 1,000π ft3 10,000π ft3 4,000π ft3 40,000π ft3

10,000π ft^3

Step-by-step explanation:

In order to even start with solving the volume of the tree trunk, you need to find the radius first.

By using the formula "r = C/2π", you can find the radius. The C stand for the circumference of the redwood tree trunk.

r = 20/2π

r = 10π

You do not need to continue any further because the question does no require you to solve for pi.

Now you can use the cylinder volume formula (V = πr^2*h) and find the approximate volume of the redwood tree trunk.

V = π10^2*100

V = π100(100)

V = 10,000π feet^3

The approximate volume of the redwood tree trunk is 10,000π ft^3

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
