Question

The diameter of the two circular ends of the bucket are 44cm and 24cm.the height of the busket is 35cm.find the volume of the bucket

Answer 1

Given the height of the bucket = 35cm.

Given the diameter of 1 circular end of bucket = 44 cm, Then the radius r = 22cm.

Given the diameter of another end = 24 cm, Then the radius r = 12 cm.

We know that Volume of the bucket = 1/3pir^2h

                                                           = 1/3 * 22/7 * ((22)^2 + (12)^2 + 22 * 12) * 35

                                                           = 35/3 * 22/7 * (484 + 144 + 264)

                                                           = 35 * 22 * 892/3 * 7

                                                           = 32706.6 cm^3

 

                                                           = 32.7 litres.

The volume of the bucket = 32.7 L.

Hope this helps!

Answer 2

$\frac{\pi( {r}^{2} + {r}^{2} + r \times r )h}{3}$
