Question

1. If a square has a radius of twelve, would its apothem be 6sqrt2? What will its area be? How would I solve it?


2. If triangle has a radius of 12, would its apothem be 7sqrt3? How would I find the area?


3. How would I find the area of a hexagon if it's apothem is 7sqrt3?

Answer 1

if the perimeter is p and the apothem is a, then the area is 1/2 ap

#1. correct: 12/√2
#2. hint: the triangle's altitude is 18.
#3. side is 12
