Question

Calcule o volume de cone com as dimensões:
a) r = 3,5cm e h = 13,5cm.
b) r = 20cm e h = 102cm.

​

Answer 1

Resposta:

A) 55,125π cm*3 ou 173,0923 cm*3

B) 13.600π cm*3 ou 42.704 cm*3

Explicação:

Volume do cone:

$\frac{1}{3} \pi {r}^{2} h$

A) 1 π(3,5)*2x13,5

3

1 π.12,25x 13,5

3

1 π. 165,375 -> π. 165,375

3 3

A) 55,125π cm*3 ou

π= 3,14 -> 55,124x 3,15= 173.0923cm*3

B) 1 π(20)*2x102

3

1 π.400x102

3

1 π.400x102

3

1 π.40800 -> π. 40800

3 3

B) 13600π cm*3 ou

π= 3,14 -> 13.600x 3,14= 42.704 cm*3
