Question

The radii of ends of a frustum are 14cm and 6cm respectively and its height is 6cm.
Find its curved surface area.​

Answer 1

Radius of the bigger circle = R = 14 cm

Radius of the smaller circle = r = 6 cm

Height of the frustum = h = 6 cm

Slant height of frustum = l =10cm

Lateral surface area of frustum = π (R + r) l

= 628.57 cm2

Total surface area = Lateral surface area + π R2 + π r2

=1357.71cm cube.
