Radii of the top and base of a frusturm are 14 cm and 6 cm respectivel

1.	Radii of the top and base of a frusturm are 14 cm and 6 cm respectively. Itsheight is 6 cm then find its slant height and total surface area of the frustrum.(r 3.14)
Answer» 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 =10cmLateral surface area of frustum = π (R + r) l = 628.57 cm2 Total surface area = Lateral surface area + π R² + π r² =1357.71cm cube.

Answer»

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 =10cmLateral surface area of frustum = π (R + r) l

= 628.57 cm2

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

=1357.71cm cube.
