The formula for the lateral area of a cylinder is LA = 2 x pi x r x h. (two times pi times radius times height) Using this formula, we can plug in the values and solve for the lateral area.
Plugging in the values: LA = 2 x pi x 7 x 9 Simplifying: LA = 2pi x 63 LA = 126pi yd^2
ANSWER: The 4th option - 126pi yd^2
Hope this helps!! :) If there's anything else that I can help you with, please let me know!
