Question

Calculate the volume of a cylinder where:

a.The area of the base is 30 cm 2 and the height is 6 cm. (180 cm3)

b.The radius of the base is 14 cm and the height is 10 cm.

Answer 1

(a) radius of the base = 30 cm,

height of cylinder = 6 cm

Find the volume :
------------------------
volume of cylinder = πr^2 h

= π × ( 30 )^2 ( 6 ) = π × 900 × 6 =5400π

= 5400 × 22 /7 = 16971.4 cm^3

(b) radius of the base = 14 cm

height of cylinder = 10 cm10

Find the volume :
------------------------
volume of cylinder = πr^2h

= π × (14)^2 × 10 = 1960π

= 1960 × 22/ 7 = 6160 cm^3

Answers :
--------------
(a) volume of cylinder = 16971.4cm^3

(b) volume of cylinder = 6160 cm^3

-------------------------------------------------------

Answer 2

Answer:

Step-by-step explanation:

(b) radius of the base = 14 cm

height of cylinder = 10 cm10

Find the volume :

------------------------

volume of cylinder = πr^2h

= π × (14)^2 × 10 = 1960π

= 1960 × 22/ 7 = 6160 cm^3

Answers :

--------------

(a) volume of cylinder = 16971.4cm^3

(b) volume of cylinder = 6160 cm^3
