10 conical joker caps with radius 14cm and height 48cm. Each is to be prepared from some coloured paper. Find the area of coloured paper required

Dear Student,
Given that,
Radius =r= 14 cm
height =h= 48 cm
l =√(r² +h²)
l =√(14² + 48²)
l= √(196 + 2304 )
l = √(2500)
l = 50
Curved surface area of one conical cap
= πrl
= (22/7)×(14)×(50)
= 2200 cm ²
Curved surface area of 10 conical caps
=10 × 2200 cm ²
= 22000 cm²
∴ the area of sheet required to make 10 conical caps is 22000 cm²

​​​​​​​Regards
