What is the surface area of the cylinder? Express the answer in terms of Pi?

Mathematics

Nezavi [6.7K]3 years ago

Answer:

A

Step-by-step explanation:

<u>Lids</u>

It is not clear how many lids the cylinder has or perhaps it is a solid. I'll say it has 2 lids.

The surface area of one lid = pi * r^2

r = 4

The surface area of one lid is pi*4^2 =16 pi

The surface area of two lids is 32*pi

<u>Body</u>

Length of the body = pi * d

Length of the body = 8 * pi cm

Height of the body = 18 cm

Area = l*h

Area = 8pi * 18 cm

Area = 144 pi

<u>Total</u>

Total Area = 32 pi + 144pi

Area = 176 pi cm^2

Justine and Meagan played a trivia game. Justine answered a question incorrectly and lost 7 points. Then Meagan answered correct
scZoUnD [109]

Answer:

The correct way to represent that "the opposite of Justine's score was equal to Meagan's score" is [- (-7)].

Step-by-step explanation:

We know that the opposite of the opposite of a number, say 2, is the number itself.

That is:

Opposite of 2 is -2.

Then the opposite of -2 is:

- (-2) = 2

It is provided that:

  • Justine answered a question incorrectly and lost 7 points.
  • Then Meagan answered correctly and got the opposite score.

Assume that both Justine and Meagan started with 0 score.

Justine plays first.

If Justine answered a question incorrectly, his score would be -7.

Then Meagan plays, and answers the question correctly.

So, Meagan got the opposite score.

The opposite of -7 will be [- (-7)].

Thus, the correct way to represent that "the opposite of Justine's score was equal to Meagan's score" is [- (-7)].
