Question 3 (6 points)
A company that manufactures storage bins for grains made a drawing of a silo. The silo has a conical base, as shown below:

The figure shows a silo shaped as a closed cylinder with a conical end. The diameter of the silo is 4 ft, the length of the cyl

Which of the following could be used to calculate the total volume of grains that can be stored in the silo?

a: π(2ft)2(8ft) + one over three π(2ft)2(9.5ft − 8ft)

b: π(8ft)2(2ft) + one over three π(2ft)2(9.5ft − 8ft)

c: π(2ft)2(8ft) + one over three π(9.5ft − 8ft)2(2ft)

d: π(8ft)2(2ft) + one over three π(9.5ft − 8ft)2(2ft)

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

answer: 1475
