Question

please give me the question answer​

Answer 1

Answer:

16.5 kg

Step by step explanation:

Outer radius =16/2=8cm

Inner radius=14/2=7cm

Height=35 cm

Volume =Outer volume - Inner Volume

Outer volume =

$\pi {r}^{2} h$

=22/7×8×8×35

=7040 cm^4

Inner volume

=22/7×7×7×35

=5390 cm^3

Volume =7040-5390

=1650 cm^3

Density =10g /cm^3

M=D×V

M=10×1650

M=16500 g or 16.5 kg
