Answer:
6) B
7) D
Step-by-step explanation:
6)
The surface area of a cylinder is 2 * pi * r * (r + h)
SA = 2 * 3.14 * 3.6 * (3.6 + 8.5) = 2 * 3.14 * 3.6 * 12.1 = 273.6 cm^2
7)
The volume of a cylinder is pi * r^2 * h
V = 3.14 * (3.6)^2 * 8.5 = 345.9 cm^3
Answer:
x≥ -4/55, x≤−89
Step-by-step explanation:
Step 1: Subtract 1 from both sides.
−110x+1−1≤9−1
−110x≤8
Step 2: Divide both sides by -110.
−110x/-110≤8/-110
x≥ -4/55
The 4th one goes first. Then the 2nd one. After that the 1st one goes.
If you where to simplify 4/6 you will get an equivalent fraction. So you would find a common numeral between the tw0. In this case it would be 2. So it would be 2/3 cause you would divide each number by two to get 2/3.
#3.......the 3 with the m makes it greater than 1
