Answer:

56.52

Step-by-step explanation:

volume formula of cone-v=(1)/(3)\pi r^(2)h

v=(1)/(3) (3.14) (3)^(2) (6)

v=(1)/(3) (3.14) (9) (6)

v=(1)/(3) (169.56)

v=169.56 ÷ 3

v=56.52

plz mark brainliest

let me know if yall need  help with som else :)

In analyzing a line graph, why is slope important?
Nesterboy [21]

Answer:

The slope of the line reflects the actual trend of the data

Step-by-step explanation:

<u><em>The options of the question are</em></u>

a. The slope should be negative.

b. The spacing for each axis must be chosen so that the line reflects a positive slope.

c. The slope of the line reflects the actual trend of the data.

d. The slope of a line is not important in analyzing a line graph

we know that

The slope of a line is the steepness of the line ( the change in 'y' over the change in 'x',)

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

where

y2-y1  ---> is called the rise

x2-x1  is called the run

Is important because the slope of the line reflects the actual trend of the data

<u>Geometry</u>

Volume of a Cylinder: V = πr²h

  • V is volume
  • r is radius
  • h is height

Step-by-step explanation:

<u>Step 1: Identify</u>

Radius <em>r</em> = 12 ft

Height <em>h</em> = 19 ft

<u>Step 2: Find Volume</u>

  1. Substitute in variables [Volume of Cylinder]:                                               V = π(12 ft)²(19 ft)
  2. Evaluate exponents:                                                                                      V = π(144 ft²)(19 ft)
  3. Multiply:                                                                                                           V = 2736π ft³
  4. Substitute π:                                                                                                   V = 2736(3.14) ft³
  5. Multiply:                                                                                                           V = 8591.04 ft³
