Answer:

j : 7327

Step-by-step explanation:

Split the figure into three parts 1 cylinder and hemispheres.

find the volume of each part and then in the end add them

Vol of cylinder =

$\pi \times r {}^{2} \times h \\ 3.14 \times 10 \times 10 \times 10 \\ = 3140 \\$

Find the volume of one hemisphere=

$= \frac{2}{3} \pi \times r {}^{3} \\ 2093.33$

Vol of 2 hemispheres = 2×2093.33

= 4186.66667

Total volume= 3140 + 4186.6667 = 7326.66

= 7327
