Question

Shantanu's cap is in the form of a right circular cone of base radius 7cm and height 24cm. Find the area of the sheet required to make 5 such caps​

Answer 1

Answer:

Step-by-step explanation:

given : radius= 7 cm

            height= 24 cm

l²=r²+h²  

l²=(7)²+(24)²    

l²=625

l= 25 cm

area required for 1 cap = πrl

                                       ⇒22/7 × 7 × 25

                                       ⇒ 22 × 25

                                       ⇒550 cm²

area of sheet required to make 5 such caps = 550 × 5

                                                                            ⇒2750 cm²

this is your required answer
