Question

Curved surface area of a right circular cylinder is 4.4m square if the radius of the base of the cylinder is 0.7m find its height

Answer 1

hiii

Let the height of the circular cylinder be h.
Given:
Radius of the base of cylinder(r) = 0.7 m
 
Curved surface area of a right circular cylinder  = 2πrh
Curved surface area of a right circular cylinder  = 4.4m²     (given)
2πrh = 4.4m²
2×22/7×0.7×h= 4.4
h=4.4/4.4=1m
h = 1 m
Hence, the height of the right Circular cylinder is 1 m.

 Hope this will help you....

Answer 2

Curved surface area = 2πrh
2πrh = 4.4m²
Radius of base = 0.7
2 × 22/7 × 0.7 × h = 4.4m²
4.4 × h = 4.4m²
h = 1m
