Question

a cylindrical cake has a diameter of 220mm and a height of 100mm. if the cake is cut into 12 equal slice the volume of each slice will be (x=22/7)​

Answer 1

ANSWER:

Let us find volume of the cake before cut,

vol of cylinder = pi x r^2 x h

r = 220/2 = 110 mm

= 22/7 x (110)^2 x 100

= 3 801 327,11 mm^3

vol of each piece = 3 801 327,11/12

= 316 777,26 mm^3.
