The answer is z=2m+3 so the first one is right
Hi there!
The formula for the lateral area of a cylinder is LA = 2 x pi x r x h. Using this formula, we can plug in the given values and solve for the lateral area.
WORK:
LA = 2pi x r x h
LA = 2pi x 4.5 x 17
LA = 153pi mm^2
The correct answer is the first option - 153pi mm^2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
R=12 is the solution
I don't know how to explain but it needs to be 20 characters
55/100 = (55:5)/(100:5) = 11/20
55/100 = 0.55
