Answer 1

☺☺ HERE IS YOUR ANSWER ☺☺

__________________________

Area of jokers cap = πrl

radius of cap = 7cm
height of cap = 24cn
slant height of cap = √(r^2+h^2)
=√(49+576)
=√625
=25

CSA of cap = 22/7 × 7 × 25
= 550cm^2

Area of the sheet required for 10 caps = 10 ( Area of cap)

= 10 (550)

= 5500 cm^2
