12(pie) cm 3
12(pie) cm 2
18(pie) cm 3
20(pie) cm 2

Respuesta :

V(cylinder) = πr²h

h=3 cm
r=2 cm

V(cylinder) = πr²h = π*2²*3 =12π cm³

Volume formula for cylinder
[tex]\pi \: {r}^{2} h[/tex]
replace the letters with the correct number
[tex]\pi \: {2}^{2} \times 3[/tex]
solve the exponent
[tex] {2}^{2} = 2 \times 2 = 4[/tex]
[tex]\pi4 \times 3 = 12\pi[/tex]
Every time you are finding a volume for any 3d shape, you have to cube it.
[tex]12\pi \: {cm}^{3} [/tex]
