Answer:

Step-by-step explanation:

\frac{a}{4}=\frac{b}{7}\\a=\frac{4b}{7} \\\frac{a-b}{b} =\frac{\frac{4b}{7}-b }{b} \\=\frac{4b-7b}{7b}\\ =\frac{-3b}{7b}\\ =\frac{-3}{7}

Find the sum (the total measure) of the interior angles of a 17 sided polygon??
Lunna [17]

The formula in finding the sum or the total measure of the interior angles of polygon having n sides is:

Sum of interior angles = (n – 2) 180

Where n = number of sides of the polygon

In this problem, you are asked for the sum of the interior angles of a 17 sided polygon. You have to substitute the number of sides to the formula:

Sum of interior angles = (17 – 2) 180

Sum of interior angles = (15) 180

Sum of interior angles = 2,700 degrees

The height of a cone is equal to the diameter of the base. What expression represents the volume of the cone, in cubic units?
Maurinko [17]
By definition, the volume of a cone is given by:
 V = (1/3) * (\pi) * (r ^ 2) * (h)

 Where,
 r: radius of the circular base
 h: height of the cone
 Let's define a variable:
 x: diameter of the base
 We have then that the radio is:
 r = x / 2

 The height is:
 h = x

 Substituting values:
 V = (1/3) * (\pi) * ((x / 2) ^ 2) * (x)

 Rewriting:
 V = (1/3) * (\pi) * (x ^ 2/4) * (x)

V = (1/12) * (\pi) * (x ^ 3)
 Answer:
 
An expression that represents the volume of the cone, in cubic units is:
 
V = (1/12) * (\pi) * (x ^ 3)
