Question

Which is closest to the diference in the volume of the two cylinders? A-4cm and 18cm. B-5cm and 5cm, A. 15,795 cm3 B. 2,534 cm3 C. 806 cm3 D. 512 cm3

Answer 1

Difference in the volume = 512 cm³ (Approx)

Explanation:

Given:

Radius of cylinder A (r1) = 4 cm

Height of cylinder A (h1) = 18 cm

Radius of cylinder B (r2) = 5 cm

Height of cylinder B (h2) = 5 cm

Find:

Difference in the volume.

Computation:

Difference in the volume = Volume of cylinder A - Volume of cylinder B

`Difference\ in\ the\ volume = \pi (r1)^2(h1)- \pi (r2)^2(h2)\\\\Difference\ in\ the\ volume = \pi (4)^2(18)- \pi (5)^2(5)\\\\Difference\ in\ the\ volume = \pi (16)(18)- \pi (25)(5)\\\\Difference\ in\ the\ volume =905.3-392.5\\\\Difference\ in\ the\ volume = 512.8`

Difference in the volume = 512 cm³ (Approx)
