Answer:

125π km³

Step-by-step explanation:

We are to find the Volume of a cylinder

From the question:

Height of the cylinder = 5km

Radius of the cylinder = 5 km

The volume of a cylinder =

πr² h

Hence:

π × 5² × 5

= 125π km³

The volume of the cylinder = 125π km³

Option d is the correct option

You need a mean of at least 90 points to advance to the next round of the touch-screen trivia. What score in the fifth game will
lianna [129]

Answer:

At least 98 is needed in the 5th game

Step-by-step explanation:

The missing parameters are:

Game\ 1 = 95

Game\ 2 = 91

Game\ 3 = 77

Game\ 4 =89

Mean = 90 at least

Required

The score in game 5 to make you advance

Mean is calculated as:

Mean = \frac{\sum x}{n}

So, we have:

Mean = \frac{95 + 91 + 77 + 89 + Game\ 5}{5}

Mean = \frac{352 + Game\ 5}{5}

The mean must be at least 90.

So, we have:

\frac{352 + Game\ 5}{5} \ge 90

Multiply both sides by 5

5 * \frac{352 + Game\ 5}{5} \ge 90 * 5

352 + Game\ 5 \ge 450

Make Game 5 the subject

Game\ 5 \ge450 - 352

Game\ 5 \ge 98

<em>At least 98 is needed in the 5th game</em>

elena-s [515]

Answer:

The answer to your question is 10 in

Step-by-step explanation:

Data

Circumference = 20π in

Diameter = ?

Formula

Circumference = 2πr

Process

1.- Equal the formula to the value

                     2πr = 20π

2.- Solve for r

                        r = 20π/2π

3.- Simplification

                       r = 10/2

4.- Find the diameter

           diameter = 2r

           diameter = 2(10/2)

           diameter = 10 in

9=7+a a+8=b+5 value of b
kvv77 [185]
B is 5, you can solve this by first finding the value of a, which is 2, and then plug it into the other equation. 8+2=10 so we must also make the other side 10. We then do 10-5=5, 5 is the value of b
