cross area calculus

Question

for the function; 𝑦=2sec(𝑥).

Identify the correct description of the cross section perpendicular to the 𝑥-axis located at 𝑥.

a)The cross section at location 𝑥 is a circle of radius 𝑅=2.

b)The cross section at location 𝑥 is a circle of radius 𝑅=2sec(𝑥).

c)The cross section at location 𝑥 is a circle of radius 𝑅=2sec(𝑥)−2.

d)The cross section at location 𝑥 is a circle of radius 𝑅=sec(𝑥).

Answer 1

Hi Maria,

Is there possibly a bit more context to this question? It sounds like there's some rotation happening, but I don't know if it's around the x-axis or y-axis. If I'm to make a guess, it sounds like (b) is what they might be looking for, but that depends on the full question they're trying to ask.
