Answer:
15386 sq.m
Step-by-step explanation:
given-
radius of cylindrical box= 70cm
height= 1m =100cm
to find-
the area of metal sheet required to make that cylindrical box.
solution-
area of cylinder=π × r × r × h
area= 3.14 × 70 × 70 × 100
= 314 × 4900
area= 1538600 sq.cm = 15386 sq.m
area of cylindrical box is 15386 sq.m hence metal sheet of same area will be required to make the box.
therefore, area of metal sheet required is 15386 sq.m
