Answer 1

Answer:

3.

i) curved surface area ii) total surface area. i) volume (t = 3.14)

The circumferences of circular faces of a frustum are 132 cm and 88 cm and its

height is 24 cm. To find the curved surface area of the frustum complete the

22

following activity. (r =

r )

circumference, = 2nr = 132

132

T =

277

24 cm

circumference = 2ter, = 88
