Question

Find the volume of right circular cylinder if radius of its base and its height are 1.4cm and 2dm respectively.​

Answer 1

Answer:

Appropriate question:-

•Find the volume of right circular cylinder if the radius of its base and height are 1.4cm and 2dm respectively

Given:-

=>Radius of the base of the cylinder=1.4cm

=>Radius of the base of the cylinder=1.4cmHeight of cylinder=2dm=20cm

We know that:-

=>Volume of cylinder:-(22/7 r²h)

Solution:-

=>Volume of cylinder:-22/7 r²h=22×1.4×1.4×20/7=123.2cm²

Answer:-

•Hence the volume of cylinder=123.2cm²

Used formulas:-

•Volume of cylinder:-(22/7 r²h)

•Dm to Cm:-Dm×10

Points to remember:-

The cylinder has three major quantities, based on which we have the formulas.

1.Lateral Surface Area or curved surface area.

2.Total Surface Area.

3.Volume.

Answer 2

Answer:

Radius of base of cylinder (r) = 1.4cm

Height of the cylinder (h) = 2dm = 20 cm

we know

Vol of cylinder (V) = π r2 h

= 22/7x1.4x1.4x20 = 123.2 cm2
