radius of base 14dm and height 15m
Answers
radius of base= 14dm = 14/10 = 1.4 m
height = 15m
please complete your question....
Step-by-step explanation:
At first,
We will convert the radius into metre
Radius = 14dm = 1.4m
Now,
In order to find volume we will use the following formula:
Volume of a cylinder =
Where,
‘r’ = radius of the base
‘h’ = height of the cylinder
Hence,
Volume of the cylinder =
= 22× 0.2× 1.4× 1.5
= 92.4cm3
Now,
In order to find curved surface area we will use the following formula:
Curved surface area of cylinder =
Where,
‘r’ = radius of the base no
‘h’ = height of the cylinder
Hence,
Curved surface area of cylinder =
= 22× 2× 0.2× 1.5
= 132cm2
Now,
In order to find the total surface area we will use the following formula:
Total surface area of cylinder =
Where,
‘r’ = radius of the base
‘h’ = height of the cylinder
Hence,
Total surface area of cylinder =
=
= 22× 2× 0.2× 2.9
= 144.32cm2
Find the volume, curved surface area and total surface area of each of the cylinders whose dimensions are:
radius of the base = 14 dm and height = 15 m
