Question

What is the approximate surface area of the larger cone?

467.5 square yards

267.1 square yards

152.7 square yards

817.8 square yards

Answer 1

radius of larger cone = 21x5/12 = 8.75
curve surface area = (pi) r l = (pi) (8.75)(21) = 577.2677
total surface area = curved area + based area = 577.2677 + (pi)r^2 = 577.2677 + (pi)(8.75)^2 = 817.8
