The volume of a cylinder is given by:
 V = pi * r ^ 2 * h
 Where,
 h: height
 r: Radius
 Substituting the values we have:
 V = pi * (3) ^ 2 * (8)
 Rewriting:
 V = pi * (9) * (8)
 V = 72pi cubic units
 Answer:
 
V = 72pi cubic units

Nichior compared the slope of the function graphed to the slope of the linear function that has an x-intercept of 2/3 and a y-in
marusya05 [52]

Answer:

The slope of f(x) is 1.5

Step-by-step explanation:

step 1

Find the slope of the linear function that has an x-intercept of 2/3 and a y-intercept of -1

so

we have the points

(2/3,0) and (0,-1)

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

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

substitute the values

m=\frac{-1-0}{0-2/3}

m=\frac{-1}{-2/3}

m=\frac{3}{2}=1.5

step 2

Find the slope of the function graphed

take the points

(0,-1) and (3,6)  approximately

substitute in the formula

m=\frac{6+1}{3-0}

m=\frac{7}{3}=2.33

step 3

we know that

f(x) represents the function with the smaller slope

The smaller slope is 1.5

therefore

The slope of f(x) is 1.5
