Step-by-step explanation:
2πrh+2πr²=surface area
2π(3)(6)+2π(3²)
36π+18π
54π
Step-by-step explanation:
60% = 18 +
20% = 6 ( cos its 1/3)+
20% = 6 =
100% = 30
Answer:
48
Step-by-step explanation:
Signals during a multiplication of two numbers:
They have the same signal: The multiplication is positive.
They have different signals: The multiplication is negative.
3 times (-8) times (-2)
First 3*(-8):
Different signals, so negative. 3*8 = 24. So the answer is -24.
Then:
3*(-8)*(-2) = (-24)*(-2)
Same signal, so positive. 24*2 = 48. The answer is 48.
