Question

What is the curved surface area (C.S.A) for frustum of cone whose bigger dia 12 cm and smaller dia 6 mm and slant height 14 cm

Answer 1

Dear Student,

◆ Answer -

CSA = 277 cm^2

◆ Explaination -

# Given -

R = 12/2 cm = 6 cm

r = 0.6/2 = 0.3 cm

l = 14 cm

# Solution -

Curved surface area of frustum of cone is -

CSA = π(R+r)l

CSA = 3.142 × (6 + 0.3) × 14

CSA = 277 cm^2

Therefore, curved surface area of frustum of cone is 277 cu.cm.

Thanks dear...
