Answer:
The Answer is "4 inches per year"
Step-by-step explanation:
To find the Average Rate of Change, you use:
So when you insert the numbers from the table, you get:
After solving the answer you get is 4. So the avg rate of change is 4 inches per year.
<em>6 + 7r - 4 </em>× <em>11
</em>=<em> 7r + (6-4) </em>× <em>11
= 14r+11</em>
Answer:
531.167 ft²
Step-by-step explanation:
Given data
Dimension of pool
Diameter =24ft
Radius =12ft
If the cover must hang by 1ft around, then the diameter is 26ft
Radius =13ft
Area of cover = πr²
Substitute
Area = 3.142*13²
Area =3.143*169
Area =531.167 ft²
Hence the minimum area is 531.167 ft²
This is the formula for the surface area of a cylinder including the ends, like the total surface area of a can of peas.
S = 2·π·r² + 2·π·r · H
Divide each side by 2·π·r :
S/2·π·r = r + H
Subtract r from each side :
H = (S/2·π·r) - r
or
H = (S - 2·π·r²) / (2·π·r)
