Radius=7cm
Height=24cm
we know that ,
slant height=√(h²+r²)
l=√(24²+7²)=√(576+49)=√625=25cm
l=25cm
Total surface are of cone=πr(l+r)
Total surface area=(22/7)×7(7+25)
Total surface area=(22/7)×7×32
Total surface area=704cm²
Hence metal sheet required to make cone including base=704cm²
Capacity of cone = 1/3 × πr²h
=1/3 × 22/7 ×7×7
=1283.33cm²
