Question

13.
Find the volume, the curved surface area and total surface area of a cone,
given that
radius of base = 3.5 m and height = 12 m
radius of base = 0.7 m and slant height 2.5 m
(iii) radius of base 21 cm and slant height 35 cm
(iv) height = 24 cm and slant height = 25 cm
(v)
perimeter of base = 88 cm and height = 48 cm.

Answer 1

Answer:

let radius =r, height=h,slant height =l

volume =1/3πr^2h

C.S.A = πrl

T.S.A=πrl+πr^2

Answer 2

Answer:

radius of base = 0.7 m and slant height 2.5 m
