Dimensions of Cap
Radius r = 7 Cm
Slant Height l = 15 Cm
Thus
Area of Hat = pi r * l
= 22/7 * 7 * 15
= 360 Cm^2
Cos of Hat = 360 * 50
= 18000
Radius r = 7 Cm
Slant Height l = 15 Cm
Thus
Area of Hat = pi r * l
= 22/7 * 7 * 15
= 360 Cm^2
Cos of Hat = 360 * 50
= 18000

Answer:
CP=180000 paise
Step-by-step explanation:
Given : Few children of economically weaker section used recycled paper to make conical party caps with radius 7 cm and slant height 15 cm to sell on a street stall.
The selling price of a cap is 50 Paisa per cm square which is while it is cost rupees 10 per 100 cm square.
To find : How much profit they would be earning by selling 50 caps?
Solution :
Dimensions of Cap
Radius, r = 7 cm
Slant Height, l = 15 cm
Area of Hat is given by,
A=π * r * l
A= 22/7 * 7 * 15
A = 360 cm²
The selling price of a cap is 50 Paisa per cm square which is while it is cost rupees 10 per 100 cm square.
Cost of Hat = 360 * 1000/100
Cost of Hat = 3600 paise
Cost of 50 caps = 3600*50=180000 paise
