Question

Curved Surface area of a right circular qilinder
is 4.4m2 if the radius of the base of the cylinder
is 0.7m find & its height.
​

Answer 1

Answer:

height =1 m

Step-by-step explanation:

curved surface area= 2πrh

4.4m sq.= 2*22/7*0.7*height

=2*22/7*7/10*height

( 7 will be cut by 7)

= 2*22*1/10*height

=44/10*height

4.4m sq. =4.4*height

height=4.4/4.4

(after cutting 4.4 with 4.4 we get 1/1)

therefore height=1

Answer 2

Step-by-step explanation:

C.S.A = 2πrh = 2*(22/7)(0.7)H

4.4H = 4.4

H = 1 m
