Answer:

2^2 = 4

4 x 3.14 = 12.56

12.56 x 2 (since there are two circles on the cylinder) = 25.12

Now let's find the circumference of one circle and multiply it by the height to get the round surface area!

2 x 3.14 x 2 = 12.56(circumference)

12.56 x 8(height) = 100.48

Now add both the surface areas!:

25.12 + 100.48 = 125.6 in2 is your answer.

Answer:

100(x - 1)

Explanation:

Let's begin writing down everything

(X×(-11)+5)×(-9)+X-55

Now we can multiply

-9(-11X+5)+X-55

99X-45+X-55

And so we get

100X-100

Factorize 100

100(x-1)
