Question

What is the area of a cylinder with radius 1,2 m and height 2,3 m?

Answer 1

Answer:

A≈18.85

r Radius

1

h Height

2

Unit Conversion:

Solution

A=2πrh+2πr2=2·π·1·2+2·π·12≈18.84956

Answer 2

Answer:

diameter = 2.4m, radius = 1.2 m, height= 2.3m , π value is not given

Step-by-step explanation:

solution .....

area of cylinder = 2 π r (r+ h)

= 2 π 1.2m ( 1.2m + 2.3m)

= 2 π 1.2m ( 3.5 m)

= 2 π 4.2 m

= 8.4 π m sq

since π value is not given therefore the area of cylinder is 8.4π m sq.
