Question

the radius of a circular box is 14cm . what should be the length of the tape required to wrap once around the pipe​

Answer 1

Answer:

88 cm

Step-by-step explanation:

curved surface area of pipe= 2πrh= 2×22/7×14×h = 22×4×h= 88h cm2 .

area of tape must be equal to area of rectangular tape= L×b

;. 88h= L × h ;

L = 88h/h= 88cm .

here ,breadth is equal to height of cyclindrical pipe. b=h
