Question

Hemispherical bowl of radius 30 cm filled with soap paste to made cylindrical soap cakes of diameter 10cm and height 2cm how many cakes we get?

Answer 1

Answer:

Here

In hemisphere. radius= 30cm

volume of hemisphere = 2/3 π r^3

= 2/3 *π(30)^3

=18000π

In each cylindrical swalpa cakes

diameter=10cm. radius = 5cm. height = 2cm

let the number of soap cakes= 'n'

volume of hemisphere = n * volume of cylinder

18000π = n * π r ^2h

18000 = n * 5^2(2)

18000= n* 25(2)

18000 = n* 50

18000/50 = n

360 = n

n=360

so number of saop cakes = 360
