Answer:
Step-by-step explanation:
1) volume of the cylinder= pie x r² x h
= 22/ 7 /10.5 x 10.5 x 8
= 22 x 1.5 x 10.5 x 8
= 2772cm²
2) volme of the cylinder = pie x r² x h
= 22/7 x 2.5 x 2.5 x 7
= 22 x 2.5 x2.5
= 137.5 cm²
3) volume of the cylinder= pie x r² x h
= 22/7 x 4.2 x 4.2 x 5
= 22 x 0.6 x 4.2 x5
= 277.2 cm²
4) volume of the cylinder = pie x r² x h
= 22/7 x 5.6 x 5.6 x 5
= 22 x 0.8 x 5.6 x 5
= 492.8 cm²
