Answer:

207.24 or 66pi

Step-by-step explanation:

The combined area of the bases = 2 * 3^2 * pi = 18 pi

The area of the side is 3*2*8*pi = 48 pi

48 pi + 18 pi = 66 pi

66 * 3.14 = 207.24

Answer:

Surface Area = 207.24

Step-by-step explanation:

The formula for SA of a cylinder is 2πr² + 2πrh

Here the equation would be (2 * 3.14 * 9) + (2 * 3.14 * 3 * 8) = 207.24

Three times the sum of a number and 15 is 24

allsm [11]

Answer:

$\huge\boxed{\sf x = -7}$

Step-by-step explanation:

Let the number be x

So,

=> The sum of number and 15 is x + 15

=> Three times will be 3(x+15)

Given that it equals 24

So, the given condition is:

3(x+15) = 24

Resolving Parenthesis

3x + 45 = 24

Subtracting 45 to both sides

3x = 24 - 45

3x = -21

Dividing both sides by 3

x = -7
