Question

A joker cap radius=7 cm and length,height=25 find the area of material used in 12 caps

Answer 1

HEY Buddy.....!! here is ur answer

Given that : Radius of a cap = 7 cm and

Slant Height = 25cm

Then curved surface area of one cap = πrl
where, r = radius and I = slant Height

=> 22/7 × 7 × 25 { π = 22/7 }

=> 22×25 = 550 cm²

Area of 12 caps = 12 × 550 = 6600cm²

I hope it will be helpful for you...!!
