Answer 1

Resposta:

letra: d

Explicação passo-a-passo:

Primeiro o volume do cilindro

************************************************

V = $\pi .r^{2} . h$

V = $\pi .10^{2} . 30$

V = $\pi .100.30$

V = 3000$\pi cm^{3}$

**************************************************

Agora vamos calcular o volume do cone

V = $\frac{\pi.r^{2}.h }{3}$

V = $\frac{\pi.10^{2} 30 }{3}$

V = $\frac{3000\pi }{3}$

V = $1000\pi cm^{3}$

******************************************************

Volume descartado

3000$\pi$ - 1000$\pi$ = 2000$\pi= 2000.3,14 =$ 6280$cm^{3}$

letra: d  espero ter ajudado!!!
