r =d/2
r = 8/2
r= 4 m

V= πxrxrxh
V= 3.14 x 4 x 4 x 10
V= 50.24 m^2 x 10 m
V= 502.4 m^3

V= 502.4 m^3/2
V= 251.2 m^3




r= d/2

r= 5

V= π x r x r x h
V= 3.14 x 5 x 5 x 30
V= 78.5 cm^2 x 30 cm
V= 2355 cm^3

r= d/2
r= 8/2
r= 4

h = V/ π x r x r
h = 2355 cm^3/ 3.14 x 4 x 4
h = 2355 cm^3/ 50.24 cm^2
h= 46.875 cm or 46.9 cm

Chapter 7.4


V= π x r x r x h

V= 3.14 x 0.5 x 0.5 x 10

V= 0.785 m^2 x 10 m

V= 7.85 m^3

V= π x r x r h

V= 3.14 x 0.4 x 0.4 x 10

V= 0.5024 m ^2 x 10 m

V= 5.024 m^3

V= 7.85 m^3 - 5.024 m^3 v= 2.826 m^3

Cylinder Volume and Volume Problems

a)

d/2 = r

10/2 = r

5cm = r

V= (π . r . r).hr

V= 3.14 . 5 . 5 = 78.5cm²
V= 7.85cm² . 20cm= 157cm³

b)

d/2= r

1/2= r

0.5m= r

V= (π . r . r).h

V= 3.14 X 0.5 X 0.5 = 0.785cm²
V= 0.785cm² . 1 = 0.785cm³

c)

d/2= r

18/2= r

9cm= r

V= (π . r . r).h

V= 3.14 . 9 . 9= 254.34cm²

V= 254.34cm² X 7.5cm= 1907.55cm³

First Container

d/2= r

20/2= r

10cm= r

V= (π . r . r).h

V= 3.14 . 10 .10= 314cm²

V= 314cm² X 40cm= 12560cm³

Second Container

d/2= r
30/2= r

15cm= r

V= (π . r . r).h

V= 3.14 X 15 X 15= 706.5cm²
V= 706.5cm² X 20cm= 14130cm³
