These are two questions and two answers.
Question 1. Area of an hexagon with a radius of 8 and an apothem of 4√3.
Answer: 96√3 unit²
Explanation:
1) Divide the hexagon in 6 equilateral triangles.
2) The side of each equilateral triangle is equal to the given radius: 8 units.
3) The height of each equilateral triangle is equal to the apothema: 4√3 unit.
4) The area of each equilateral triangle is:
base × heiight / 2 = 8 unit × 4√3 unit/ 2 = 16√3 unit²
5) The area of the hexagon is 6 times the area of one equilateral triangle:
6×16√3 unit²= 96√3 uni²
Question 2. Area of a madallion.
Answer:863.94 in²
Explanation:
1) The shape of the blue part is a ring with the outer radius of the circumference of 113.097 in and the inner radius equal to 7 in.
2) Outer radius
circumference = 2π r = 113.097 ⇒ r = 113.097 in / (2π) = 18 in
3) Area of the outer circle = π r² = π (18 in)² = 1017.88 in²
4) Area of the inner circle, with r = 7in = π r² = π (7in)² = 153.94 in²
5) Area of the ring (blue part) = 1017.88 in² - 153.94 in² = 863.94 in²
