Answer:

The answer to your question is below

Step-by-step explanation:

1.- Find the volume of the cylinder

Data

diameter = 9 cm

radius = 4.5 cm

height = 15 cm

Formula

V = πr²h

V = π(4.5)²(15)

V = 303.75π This is te answer for the volume in terms of π

= 952.78 cm³

2.- Find the volume of the cylinder

height = 40 yd

radius = 12 yd

Formula

V = πr²h

V = π(12)²(40)

V = 5760π This is te answer for the volume in terms of π

= 18086.4 cm³

3.- What is the height .......

height = q

side length = r

4.- Volume of a pyramid

Volume = Area of the base x height

Area of the base = 11 x 11 = 121 cm²

Volume = 121 x 18

Volume = 2178 cm³

Answer:

1. 953.775 cm³

2. 18,086.4 yd³

3. height: q ; side: r

4. 726 cm³

Step-by-step explanation:

1. Volume = pi × r² × h

= 3.14 × (9/2)² × 15

= 953.775 cm³

2. Volume = pi × r² × h

= 3.14 × 12² × 40

= 18086.4 yd³

3. height: q ; side: r

4. Volume = ⅓ base area × height

= ⅓ × 11² × 18

= 726 cm³

To determine the median, we need to set up our numbers from least to greatest, and then place T in later to figure out what T is.
8, 9, 9, 9, 10, 11, 12, 15. Cross out the smallest number with the largest number.
9, 9, 9, 10, 11, 12.
9, 9, 10, 11.
9, 10.
9.5 is our median currently.
Since we need to get a number after 10 to make 10 the median, let's use 12.
8, 9, 9, 9, 10, 11, 12, 12, 15.
9, 9, 9, 10, 11, 12 ,12.
9, 9, 10, 11, 12.
9, 10, 11.
10 is now our median since we inserted 12 into our list.
Your answer is 12.
I hope this helps!
