Answer :

Base radius (r) = 7 cm

Height (h) = 24 cm

∴ Slant height (l) = = = = = 25 cm

∴ Curved surface area of a cap = πrl = = 550 cm

∴ Curved surface area of 10 caps = 550 × 10 = 5500 cm

Hence the area of the sheet required to make 10 such caps is 5500 cm

Height (h) = 24 cm

∴ Slant height (l) = = = = = 25 cm

∴ Curved surface area of a cap = πrl = = 550 cm

^{2 }∴ Curved surface area of 10 caps = 550 × 10 = 5500 cm

^{2 }Hence the area of the sheet required to make 10 such caps is 5500 cm
