2.1 , - 6/10 , -9/4 , -0.75 , 5/3 , least to greatest
WINSTONCH [101]

Answer:

-9/4, -0.75, -6/10, 5/3, 2.1

Step-by-step explanation:

This is a lot easier to figure out if you simplify the fractions and then change them to decimals

So -9/4 = -2 1/4 or -2.25

-0.75

-6/10 = -0.60

5/3 = 1 2/3 or 1.67

2.1

When you are ordering negatives, the biggest negative is the least. That is why -9/4 (-2.25) is the least number out of the five given.

The next one would be -0.75, because it is the second biggest negative fraction.

The next one is -0.60 because that is the 3rd biggest negative fraction (or the smallest because this is the last negative)

Now, because we're in the positives we start with 1.67, because it is smaller than the other number.

2.1 is our last number, so it is the greatest!

I hope this helped :)

100 points!! Brainliest if correct!!
ladessa [460]

Answer:

4π(w+1)(w-1)

Step-by-step explanation:

The total surface area of the cylinder

= 2 x area of base circle + area of vertical surface

= 2x pi x radius^2 + 2x pi x radius x height

= 2π(w-1)^2 + 2π(w-1)(w+3)

= 2π[w^2-2w+1 + w^2+2w-3]

= 2π(2w^2-2)

= 4π(w^2 - 1)

= 4π(w+1)(w-1)
