Question

Curved surface area of a cone is 308 cm and slant height is 14 cm .Find (1)radius of base

Answer 1

Answer:

Radius of base = r = 7 cm

Step-by-step explanation:

Given -

C.S.A. of cone = 308 cm

Slant height of cone = l = 14 cm

C.S.A. of cone = πrl

308 = 22/7*r*14

308 = 22*r*2

308/22*2 = r

154/22 = r

r= 77/11

r = 7 cm
