Question

A drinking glass is in shade of a frustum of a come of height 14cm. diameter of two circular ends are36cm and30cm. find the capacity of glass.

Answer 1

Answer:answer 102.6

Step-by-step explanation:

Answer 2

Answer:

12012 cm³

Step-by-step explanation:

Height of Frustum = 14 cm

Radius(R) = 36/2 = 18

Radius(r) = 30/2 = 15

SO, the capacity of glass = 1/3πh(R²+r²+Rr)

                                          = 1/3 * 22/7 * 14* [(18)²+(15)²+(18)(15)]

                                          =1/3 * 22 * 2 [(324)+(225)+(270)]    

                                          =1/3 * 44 * (819)

                                           = 44 * 273

                                           = 12012 cm³

so the volume of glass is 12012cm³
