ANSWER: Chapter 12
Find the lateral and surface area of each solid.
Round to the nearest tenth.
4. 5. SOLUTION: SOLUTION: ANSWER: The bases are regular hexagons, so each base can be
split into 6 equilateral triangles. Find the lateral and surface area of each regular
pyramid or cone. Round to the nearest tenth if
necessary.
