Question

The formula for the lateral area of a right cone is LA = rs, where r is the radius of the base and s is the slant height of the cone.

Which are equivalent equations? Select two correct answers.

s = s equals StartFraction L A Over pi r EndFraction.
s = s equals StartFraction pi r Over L A EndFraction.
s = LAr
r = r equals StartFraction L A Over pi s EndFraction.
r = LAs

Answer 1

From LA = π r s, solve for s and r:

- Solve for s: s = LA / (π r).
- Solve for r: r = LA / (π s).

So the two correct choices are:
- s = LA / (π r)
- r = LA / (π s)
