NASA is painting the nose cone of a sounding rocket with a special sealant which reduces the air-drag on the rocket. If they nee
d to do two coats of the sealant, how many square feet are they painting? Use π = 3.14.
1 answer:
Answer:
The formula for the lateral surface area (LSA) of a right cone is:
LSA = π x r x l
where: r as radius, and l as the slant height of the cone
If NASA need to do two coats of the sealant, the number of square feet that they are painting is: 2 x LSA = 2 x π x r x l
