<span>So we want to know how much clay did Joseph add after he built the cone. So the formula for the volume of the cone is V=(1/3)*pi*r^2*h where r is the radius and h is height. We know h1=12cm and r1=6cm, r2=6cm and h2=18 cm. So to get the amount of added clay Va we simply subtract the volume of the clay of the first cone V1 from the volume of the second cone V2: Vd=V2-V1=(1/3)*pi*(r1^2)*h1 - (1/3)+pi*(r2^2)*h2. Va=678.24 cm^3-452.39 cm^3= 266.08 cm^3.</span>
Answer:
Variable 
represents the slope of the equation.
Step-by-step explanation:
Given that the administrative fees that company charge is $3.50.
Also, the Zhao has a bill of $63.25.
The equation used by Zhao is
We can compare the equation of a line in the slope-intercept form.
We can see the y-intercept is $3.50 that is a fixed cost. And the company charged $63.25 that is the dependent variable.
Also, variable that is the rate per kilowatt-hour (kWh) represents the slope of the equation.

Answer:
$1,210
Step-by-step explanation:
$28,000 - $2,100 = $25,900
$25,900 - $5,000 = $20,900
1.5% × $1,000 = $15
3% × $2,000 = $60
4.5% × $2,000 = $90
5% × $20,900 = $1,045
$15 + $60 + $90 + $1,045 = $1,210
