Surface = 2 x PI x r x H + 2 x PI x r^2
= 2 x r x h + 2 x r^2
= 2 x 6 x 12 + 2 x 6^2
= 144 + 72
= 216 PI in^2
Answer is A
Simplify both sides of the equation and isolate the variable!
The answer would be 3.6
Answer:
Step-by-step explanation:
t is the number of hours
12.24+0.11t = 12.74-0.15t
0.11t + 0.15t = 12.74 - 12.24
0.26t = 0.5
t= 0.5/0.26
t= 1.92 hours
approx to 2 hours
I would but I’m like really bad at math so
