Question

The dianter of a cone is 14 cm lind It slint hight is 4cm find the area of its curled
surface

Answer 1

Solutions :-

Given :
Diameter = 14 cm
Radius = r = 14/2 = 7 cm
Slant height = l = 4 cm


Find the curved surface area of cone :-

Curved surface area of cone = πrl sq. units
= 22/7 × 7 × 4 cm²
= 22 × 4 cm²
= 88 cm²


Hence,
Curved surface area of cone = 88 cm²

Answer 2

hey
________________

curved surface area of cone = πrl

given slant height (l) = 4cm
radius = 14/2=7cm

now CSA = 22/7×7×4
=22×4
=88 cm ^2

for the diagram refer to the attachment

hope helped
