I think it is 142cm^2. What I did to work this out is, 236 divided by 5= 47.2 ( to get the surface area of a 1cm cylinder) then multiply by 3 = 141.6 then round
Answer: 1. 2 2. 4 3. 9
Step-by-step explanation: Hi there!
First, we need to set up our equation by combining like terms.
x+2x+4x+1=15
7x+1=15
Then subtract 1 on both sides
7x=14
Then divide by 7
x=2
So x=2
Put that into all of the x values on the piece of steel to get 2, 4, 9.
Hope this answer helps you!
It's basically multiplication by 3. 3x3 9x3 27x3 etc
The answer is 20,
