Alright so what our area?
@some.random.cool.kid you think you can help me with this problem
Not the answer you are looking for? Search for more explanations.
you have your height as 8.3
so fill this in A=πr(r+h2+r2)=π·2.7·(2.7+8.32+2.72)
well first you are is A≈96.94cm²
oh yeah ok
oh yeah ok
alright so do you think you can try the next step on your own? I will be trying to solve it while you do k.
r = 2.7 m
h = 8.3 m
s = 8.72812 m
V = 63.3628 m3
L = 74.0345 m2
B = 22.9022 m2
A = 96.9367 m2
I believe you multiply this to get part however 96.94 x 8.3 wont give you your answer their is another step I believe.
radius x height = 22.41 I belive your closet answer is 93cm^2 But can also be 164cm^2 so please challenge me if im wrong but its between both of those answers.
@Nnesha or @nincompoop you guys might able to explain this better than I ...
got it i believe your answer is 93
