(Please show the steps if possible)

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

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

Complete the solution of the equation. find the value of y when x equals to 1 9x-5y=29
