Answer:

Step-by-step explanation:
We are given the temperature inside the machine from startup until 10 seconds later, the formula is:

We want to know at what time t the temperature inside the machine will be equal to 128 °C.
So we set:


Now, we rearrange the equation to keep terms with t on the left hand side and terms without t on the right hand side

and we simplify:


now it's easy to solve for t:

And thus we arrive to the solution.
Answer:
Diameter of cylinder = 12 cm
Step-by-step explanation:
Given:
Height of cylinder = 5 cm
Total surface area of cylinder = 3 x [Curved surface area of a cylinder]
Find:
Diameter of cylinder
Computation:
Total surface area of cylinder = 3 x [Curved surface area of a cylinder]
πr²h = 3[2πrh]
πr²h = 6πrh
Radius of cylinder = 6 cm
Diameter of cylinder = 2 x Radius of cylinder
Diameter of cylinder = 2 x 6
Diameter of cylinder = 12 cm
To find out how much he makes per week, take the amount and divide it by the week.
