Answer:
one million two hundred thirty four thousand six hundred seventy eight
Answer:
18.446
Step-by-step explanation:
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
20.75 because if you add 4.85+7.95+7.95 add that you get 20.75
