If the circumference of a circle is increased by 50%, then how much will the area be increased?
Why does the circle have 360 degrees? Does it have anything to do with the fact that a year has 365 days?
אם היקף מעגל יגדל ב-50%, אז כמה יגדל השטח?
למה למעגל יש 360 מעלות? האם זה קשור לעובדה שלשנה יש 365 ימים?
