Question

find the lateral surface area of a cone whose height is 24 cm and diameter of the base is 14 centimetre​

Answer 1

Answer:

answer is 550cm sq.

Step-by-step explanation:

so the diameter of the base is 14cm .

then base radius 14/2=7cm.

and, slant height=√(height * height) + (radius * radius)

slant height=√(24*24) +(7*7)

slant height =√576+49

slant height =√625

slant height =25cm

so now the lateral surface area of a cone = π*radius*slant height

lateral surface area of a cone= 22/7*7*25

lateral surface area=22*25

lateral surface area=550cm sq.
