Question

Um copo tem a forma de um cone com 8cm de altura e 6cm de diâmetro da base. Qual a sua capacidade em litros?

Answer 1

r = d/2

r = 6/2

r = 3

1 cm³ = 0,001 litros

75,36 cm³ = 0,07536 L

$V= \dfrac{ \pi .r^2 .h}{3} \\\\\\\\V= \dfrac{ \pi .3^2.8}{3} \\\\\\V= \dfrac{ \pi .72}{3}\\\\\\V= 24 \pi \\\\\\V=75,36\ cm^3$

Forte abraço!
