. (08.01 MC) 1. Find the volume of a cylinder with a diameter of 8 inches and a height that is three times the radius. Use 3.14
icang [17]

Answer:

602.88 in³

12

Step-by-step explanation:

Formula for volume of a cylinder = πr² · h

radius (r) = 1/2(diameter)

1. Set up the equation

radius = 4

(3.14)(4²)(3·4)

2. Solve

3.14(16)(12) = 602.88 in³

Formula for volume of a cone = 1/3πr² · h

The formula of a cone is 1/3 the volume of a cylinder. Therefore, a cone that fits perfectly within the dimensions of a cylinder would have a volume equal to 1/3 of the volume of the cylinder.

1. Set up the equation and solve

36 ÷ 3 = 12

Bongani and Jane are friends. Bongani takes Jane's maths test paper and will not tell her what her number of points is. He knows
Crazy boy [7]

Answer:

Jane has 6 points, and B has 8 points.

Step-by-step explanation:

If both of them in total have 14 points, and B has 2 more points than Jane, this means that:

B+2=14

So to find their individual number of points, you need to take 2 away from 14

14-2=12

Since these are being divided to two people, you have to divide 12 too

12/2 = 6

6 is Jane's number of points. And now to find B just add 2 points to it which is 8.

Jane=6 Bondani=8

6+8=14

Write an equation for the line shown on the graph.
Irina18 [472]

Answer:

\large\boxed{y=\dfrac{2}{3}x+1}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept → (0, </em><em>b</em><em>)</em>

<em />

The fromual of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

<em>(x₁, y₁), (x₂, y₂)</em><em> - points on a line</em>

<em />

We have the points from the graph:

(0, 1) → <em>b = 1</em> and (3, 3).

Calculate the slope:

m=\dfrac{3-1}{3-0}=\dfrac{2}{3}

Finally we have the equation of a line:

y=\dfrac{2}{3}x+1
