Answer:
Step-by-step explanation:
Radius =7cm
Height=24cm
Area of one sheet = Curved Surface Area of 1 cap
C.S.A of 1 cap =πrl
l^2 =r^2+h^2
l^2= 7X7 +24X34
l^2=625
Therefore l=under root of 625
l=25
C.S.A.= 22/7 X 7 X25. = 550
Therefore CURVED SURFACE AREA of 1 cap = 550 m^2
Sheet required to make 10 caps is equal to
550 X 10=5500
Therefore total area required to make 10 caps is equal to 5500m^2.
