Answer:
1. 2143.57 cm^3
V = 4πr^3
3
= { (3.14 x 8^3) x 4} ÷ 3
= { (3.14 x 512) x 4 } ÷ 3
= (1607.68 x 4) ÷ 3
= 6430.72 ÷ 3
= 2143.57
2. 138.16 cm^3
V= πr^2 x h
3
= { (3.14 x 2^2) x 33 } ÷ 3
= { (3.14 x 4 ) x 33 } ÷ 3
= (12.56 x 33) ÷ 3
= 414.48 ÷ 3
= 138.16 cm^3
3. 64 cm^3
V= a^3
= 4 x 4 x 4
= 64 cm^3
4. 87.92 cm^3
V= πr^2 x h
= (3.14 x 2^2) x 7
= (3.14 x 4) x 7
= 12.56 x 7
= 87.92 cm^3
5. 420 cm^3
V= w x h x l
= 4 x 15 x 7
= 420 cm^3
Hope this helps ^^
