3 years agoHow did you get 113?lilia
3 years agosame question as jim because you have to explain why and how you got your answer..
3 years ago\[2\pi*2*9 =113.097 \]
3 years agoThat covers the lateral side But what about the top and bottom?
3 years agoWell the total would be 226... but that's not an option :/
3 years agoWhat's the area of one circle?
3 years ago12.57
3 years agoDouble that to get ???
3 years agoI did and got 25.14 , so I added 25.14+113= 138.14 That is also an option :/
3 years agobut it's very close to 138.3
3 years agoso maybe there's a bit of round off error
3 years agoI'm getting 2*pi*2^2+2*pi*2*9 = 138.23007675795 which is also close to 138.2
3 years agoWeird.. So for sure the final answer wouldn't be 113 ?
3 years agodefinitely not 113
3 years agoIs there any possible way you could get 163.4 or 153.4 ??
3 years agoI don't think so since I got 2*pi*2^2+2*pi*2*9 = 138.23007675795
3 years agoYeah, so did I .. I think that's the answer; it's the only logical one.
3 years agoyeah I agree
