Answer:
251.2
I used 3.14 as pi
Step by step explanation:
SA= 2(pi*r²) + (pi*d)h
SA= 2 (
* 4² ) + (pi*8)*6
<u>you could also do this:</u>
SA=2πrh + 2πr²

Formula
---------------------------------------------
Area = Length x Width
---------------------------------------------
Find Area
---------------------------------------------
Area = 3.1 x 2.4
Area = 7.44mm²
---------------------------------------------
Answer: 7.44mm²

The method in which you do this problem would be to FOIL. First Outer Inner Last. You take the first terms and multiply them. x*x = x^2 (x to the second power). Then you do it with the rest of foil.
x*x = x^2
x*1 = x
x*3 = 3x
1*3 = 3
x^2 + x + 3x + 3 = X^2 + 4x + 3
170 cm. The unknown length on the left is 21 cm
