Question

with the given measurment find the volume of cylinder diameter=20m, height= 21cm?​

Answer 1

Step-by-step explanation:

VOLUME OF CYLINDER = πr²h

DIAMETER =2*RADIUS

20/2=RADIUS

RADIUS = 10cm

VOLUME = 22/7*10²*21

CANCELLATION OF 21 WITH 7

=22*10*10*3

=6600cm³

Answer 2

Answer :

• Volume of cylinder is 6600cm³

Given :

• Diameter = 20m
• Height = 21cm

To find :

• Volume of cylinder

Solution :

Given ,

• Diameter of cylinder = 20m
• Height of cylinder = 21cm

First we need to find the radius ,

• Radius = Diameter/2 = 20/2 = 10m

As we know that,

• Volume of cylinder = πr²h

where , r is radius 10m and h is height 21cm

》πr²h

》22/7 × (10)² × 21

》22/7 × 100 × 21

》22 × 100 × 3

》6600cm³

Hence, Volume of cylinder is 6600cm³

More Explanation :

• Curved surface area of cylinder = 2πrh
• Total surface area of cylinder = 2πr(r + h)
• Volume of cylinder = πr²h
