You can put this solution on YOUR website! what is the lateral area of a right cylinder if the radius of the base is 12mm and the altitude of the cylinder is 5 times the base radius? round your answer to the nearest whole number.
Sol'n:
LA = 2pi(rh)
h = 5r
so, LA = 2pi(rx5r)
LA = 10pi x r^2
LA = 10pi x 12^2
LA = 1,440pi
LA = 4,524 sq. mm.---anser
