can someone help me solve this problem and i i also have to use 22/7 as pi

Answer:
[tex]V = 7241.14 \: cubic \: unit[/tex]
Step-by-step explanation:
Assuming you want to find the volume.
The diagram is a sphere.
The volume is given by:
[tex]V = \frac{4}{3} \times \pi {r}^{3} [/tex]
From the diagram, r=12cm
We substitute this value into the formula to get:
[tex]V = \frac{4}{3} \times \frac{22}{7} \times {12}^{3} [/tex]
[tex]V = 4 \times \frac{22}{7} \times {12}^2 \times 4 [/tex]
[tex]V = 4 \times \frac{22}{7} \times 144 \times 4 [/tex]
[tex]V = 7241.14 \: cubic \: unit[/tex]
