Answer:
197.92 cm
Explanation:
The formula to find volume for a cylinder is V=πr^{2}h
The problem gave you the height (h): 7cm and the radius (r): 3cm and pi (π) is a constant that will automatically insert when you use the "π" button in a calculator
Now that you know that you have all your variables, you can now plug them into your formula.
V=π3^{2}7
Next, solve the equation.
V=π(9)(7)
V=π(63)
V=197.92cm
Hope this helped! :)
