Answer:
144.2 cm
Step-by-step explanation:
Length of the iron rod is 7.4cm
Radius is 3.1m
Therefore the surface area can be calculated as follows
= 2πrl
= 2×3.142×3.1×7.4
= 144.2 I'm
Hence the surface area is 144.2cm
Answer: It depends.
Step-by-step explanation:
If you are adding two negatives those two negatives will not give you a positive and if you are subtracting negatives depending on the numbers it wont give you a positive. Now when you multiply or divide two negatives that's a different story, but adding and subtracting negatives wont give you a positive.
Which value of x and y when plugged into the equation will create the same value on both sides?
The best way to do this is by trial and error.
Let's try x = 3 and y = 14.
y = 2x + 8
14 = 2(3) + 8
14 = 6 + 8
14 = 14
We got the same answer on both sides.
