Answer:

- 16

Step-by-step explanation:

The way this is given, you have to find the second term before you can fine the third.

a2 = d(n - 1) * (-2)^2

a2 = 2 * (-2)^2

a2 = 2 * 4

a2 = 8

a3 = d(3 - 1) * (-2)^3

a3 = 2 * (-2)^3

a3 = 2 * - 8

a3 = - 16

at least 4 days

Step-by-step explanation:

300 - 55 = 245

3.25 x 5 = 16.25       43.75 + 16.25 = 60

40 / 12 = 3.3333333         So you can only visit 3 days with the daily pass before it cost 40 dollars

The volume of the cylinder is C, 753.6 mm³.

To find the volume of the cylinder, in cubic millimeters, we must first convert all of the measurements into millimeters. The only measurement that isn't in millimeters is height, and 1.5 centimeters is equal to 15 millimeters. 

Now, we need to find the volume. The volume can be found by doing πr²h. Now we can substitute values and solve.

V = πr²h

V = 3.14(4)²(15)

Simplifying this, we get that V = 753.6, meaning that our answer is C, 753.6 mm³.
