Answer:
oint variation problems are solved using the equation y = kxz. ... Step 2: Use the information given in the problem to find the value of k, called the ... Example 1 – If y varies jointly as x and z, and y = 12 when x = 9 and z = 3, find z when y = 6 and x = 15. ... In this case, you need to find k when v = 120π, h = 10, and r = 6. Step 2.
