R(t) = 4t
A(r) = π(r^2)
a) A(t) = A[r(t)] = π[r(t)]^2 = π[4t]^2 = 16π(t^2)
b) t = 4,
A(4) = 16*3.14*(16)^2 = 12,861.44
First, we can write the equation of the line using the information provided:

Now, we can create a table:
Finally, we can graph the line:
Answer:
A
Step-by-step explanation:
Because you have to use the Pythagorean theorem to solve for this.
Answer:
B. 
Step-by-step explanation:
The lateral area of the right cylinder refers to the curved surface area.
The lateral area of the right cylinder does not include the two circular bases.
The lateral area is given by the formula;

The correct choice is B.
