Question

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

Answer 1

10,000πft³

Explanation:

the formula for circumference is 2πr so you put 20π equal to that and when you simplify you get 10 as your radius. The formula for a cylinder is Volume=πr²h where r is radius and h is height when you plug in your numbers the equation is V=π(10)²(100) simplify that and you get 10,000πft³
