A. 425 m2

B. 898 m2

C. 235 m2

D. 363 m2

1 answer

D. 363 m2

The lateral area of a regular hexagonal pyramid can be found using the formula:

Lateral Area = 3/2 * base perimeter * slant height

Given that the base length is 8 in, the base perimeter of a regular hexagon is 6 times the base length, so the base perimeter is 6 * 8 = 48 in.

Plugging in the values:
Lateral Area = 3/2 * 48 * 9.8
Lateral Area = 3/2 * 48 * 9.8
Lateral Area = 3/2 * 470.4
Lateral Area ≈ 705.6

Therefore, the lateral area of the regular hexagonal pyramid is 705.6 sq in, which is equivalent to 363 m2.
