Answer:
Given :
• A square paper sheet has 1025 cm long side.
to find :
Find its perimeter.
Solution :
Perimeter of square = 4 x side
==> 4 x 1025
==> 4100 cm
Extra information :
. Volume of cylinder = πr²h
T.S.A of cylinder = 2πrh + 2πr²
. Volume of cone = 1/3 Tr²h
.C.S.A of cone = πrl
• T.S.A of conе = πrl + ²
• Volume of cuboid = I xbxh
. C.S.A of cuboid = 2(1 + b)h
• T.S.A of cuboid = 2(lb + bh + Ih)
. C.S.A of cube = 4a²
• T.S.A of cube = 6a²
• Volume of cube = a³
. Volume of sphere = 4/3r³
. Surface area of sphere = 4tr²
• Volume of Hemisphere = 2/3 TTr³
• C.S.A of hemisphere = 2πr²
. T.S.A of hemisphere = 3nr²
