Answer:

Step-by-step explanation:

1.)volume of a cylinder

V=πr 2 h

d=8cm

r=8/2

r=4cm

V=3.14(4)2 (12)

V=3.14(16)(12)

V=3.14(192)

V=602.88cm

2.) volume of spherical

V=4/3πr3

V=4/3(3.14)(6)2

V=4.186 (216)

V=904 146cm

3.)

V=1/3lwh

V=1/3(52)(30)(40)

V=1/2(62,400)

V=20,800m

Answer:

V=2,411.52cm³

Step-by-step explanation:

V=πr² h

R=8cm

H=12cm

8cm×8cm=64cm

64cm×12cm =768cm

π=3.14

so 3.14 multiply to 768cm

V=2,411.52
