There were approximately 3.3 x 108 people in the United States of America in 2018. The average person consumed about 3.4 x 10 milligrams of sodium cach day. Approximately how much sodium was consumed in the USA in one day in 2018? Write answer in scientific notation.

(3.3 x 10^8) x (3.4 x 10^2) = 1.22 x 10^11

Step-by-step explanation:

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
