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 =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.

Answer:
1357.71cm cube
Step-by-step explanation:
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 cm 2
Total surface area = Lateral surface area + π R2 + π r2
=1357.71cm cube.
