What is the lateral area of a right cylinder if the radius of the base is 12 mm and the altitude of the cylinder is 5 times the base radius? round your answer to the nearest whole number.

a. 2715 mm2
b. 905 mm2
c. 3167 mm2
d. 4524 mm2

The lateral area of a cylinder is given by:
Area=πrl+2πr^2
radius,r=12 mm
length,l=5*12=60mm
therefore the lateral area will be:
Area=π*12*60
Area=2,261.95 mm^2
The area of the bases will be:
A=2*π*12^2=904.78 mm^s
The lateral area will be:
2,261.95+904.78
=3,166.73
=3167 mm^2

The answer to the question is d
