Study Notes
Geometry and Area Calculations
- Area of a circle formula: ( A = \pi r^2 )
- Increasing radius by 1% changes ( r ) to ( r + \frac{r}{100} = \frac{101r}{100} )
- New area with adjusted radius: ( A = \pi \left(\frac{101r}{100}\right)^2 = \pi \frac{10201r^2}{10000} )
- Increase in area:
- Original area: ( \pi r^2 )
- New area: ( \pi \frac{10201r^2}{10000} )
- Increase: ( \pi \frac{10201r^2}{10000} - \pi r^2 = \frac{10000\pi r^2}{10000} = 10000\pi r^2 )
- Percentage increase in area calculation:
- ( \frac{10000\pi r^2}{\pi r^2} \times 100 = 2001% )
Important Figures in Indian History
- Mahatma Gandhi: Real name Mohandas Karamchand Gandhi; key figure in India's freedom struggle; founder of Satyagraha; died on January 30, 1948.
- Pandit Jawaharlal Nehru: First Prime Minister of India; major leader in the independence movement; passed away on May 27, 1964.

- Indira Gandhi: First and only female Prime Minister of India; died on October 31, 1984.
Mathematics and Profit Calculations
- Selling price and cost price relationship:
- Selling price of 100 pens - Cost price of 100 pens = Selling price from profit on 20 pens.
- Form the equation: ( 100x - 80x = 20x )
- Profit percentage formula:
- ( \text{Profit%} = \frac{20x}{80x} \times 100 = 25% )
