Answer:

7.57 cm

Step-by-step explanation:

Volume of a cylinder = πr²h

π = 3.14

r= radius

h = height

1,800 = 3.14 x r² x 40

r² = 1800 /(3.14 x 40)

r² = 14.33121

√14.33121 = r

r = 3.785658 cm

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

Diameter = 2 x 3.785658 cm = 7.57cm

What is the slope of the following graph? (write your answer as a fraction unless divided by 1. Do not use spaces in your answer
alexira [117]

The slope of the graph is 4/5

<h3>How to determine the slope</h3>

Using the formula

Slope = Δ y-axis / Δ x- axis

y2 = -4

y1 = 0

x2 = -5

x1 = 0

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

Substitute the values into the formula

<em>Slope = </em>\frac{-4 - 0}{- 5 - 0}

Slope = \frac{-4}{-5}

Slope = \frac{4}{5}

Therefore, the slope of the graph is 4/5
