Answer:
4 hours
Step-by-step explanation:
5000 divided by 1135
S A = r² π + 2 r π h
192 π = r² π + 2 r π h / : π
192 = r² + 2 r h
2 r h = 192 - r²
h = (192 - r² ) / 2 r
V = r² π h = r² π ( (192 - r² ) / 2 r ) =
= π / 2 ( 192 r - r³ )
So 5k-7=-7
You need to do the opposite of addition,which is subtraction so...
5k-7=-7
+7
__
K=0
and to double check it,replace the (or variable) with our answer (0)...
so
5×0-7=-7
solve the problem...and
-7=-7√
(0,3)
