Answer:

Step-by-step explanation:

Total surface area = 2πr(r+h)

If the total area of the bigger cylinder is 400cm² and radius is 4cm, then;

400=2(3.14)(r)(r+4)

400= 6.26r(r+4)

400=100.48 + 25.12h

299.52 = 25.12h

H = 299.52/25.12

H = 11.92cm

For the smaller cylinder

The height is calculated as;

H/h = R/r

11/92/

aliina [53]
\begin{gathered} x=\text{cans of frozen OJ} \\ f(x)=\text{Total cost(\$)} \\ f(x)=1.25x \\ f(1)=1.25(1)=1.25 \\ f(2)=1.25(2)=2.50 \\ f(3)=1.25(3)=3.75 \\ f(4)=1.25(4)=5.00 \end{gathered}

Independent variable = x(Cans of frozen OJ)

dependent variable = y(total cost)
