9th Maths | Ch6, Ep8: Measuring Space: Perimeter and Area, Pg no 149 to 150, Kadak explanation

9th | Mathematics | Chapter 6 : Measuring Space: Perimeter and Area episode 8| Beyond the Notz 🔥 | क🦆(KADAK) explanation by Naman Sir 00:02 - Exercise Set 6.3, Page no.148 Question 7: A chord of a circle of radius r subtends an angle of 60° at the centre of the circle. Show that the area of the corresponding minor segment of the circle is equal to πr²(1/6 − root3/4). 01:45 - End-of-Chapter Exercises, Page no.149 Question 1: Identities in algebra can sometimes be shown as area relationships. For example: The figure shown corresponds to the identity (a + b)2 = a2 + 2ab + b2 . Do you see how? Draw figures corresponding to the identities (a + b)(a – b) = a2 – b2 and (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca. 03:35 - End-of-Chapter Exercises, Page no.149 Question 3: An isosceles triangle has base 10 cm, and its area is 60 cm2 . What are the lengths of the equal sides? 15:57 - End-of-Chapter Exercises, Page no.149 Question 4: The area of a right-angled triangle is 54 sq. cm. One of its legs has length 12 cm. Find its perimeter. 19:29 - End-of-Chapter Exercises, Page no.149 Question 6: The sides of a triangle have lengths 7 cm, 24 cm, 25 cm. Find the area of the triangle in two different ways. 23:20 - End-of-Chapter Exercises, Page no.149 Question 7: If the wheel of a bicycle has a diameter of 60 cm, find how far a cyclist will have travelled after the wheel has rotated 100 times. 29:39 - End-of-Chapter Exercises, Page no.150 Question 8: Find the area of a quadrant of a circle whose circumference is 66 cm. 40:45 - End-of-Chapter Exercises, Page no.150 Question 10: Two rectangles have the same area and the same perimeter. Does this mean that they are congruent to each other? Homework Question: End-of-Chapter Exercises, Page no.149,150 Question 2: An isosceles triangle has perimeter 40 cm; the equal sides are 15 cm each. Find the area of the triangle. Question 5: The sides of a triangle are in the ratio 2: 3: 4, and its perimeter is 45 cm. Find its area. Question 9: The wheel of a car has an outer radius of 28 cm. Calculate how far the car travels after one complete turn of the wheel, and how many times the wheel turns during a journey of 1 km. *********RELATED VIDEOS********* CONTINUE MORE OF THIS CHAPTER IN Episode 9 PLAYLIST LINK:    • Class 9th Mathematics   EPISODE 1 LINK:    • 9th Maths | Ch 6, Ep1: Measuring Space: Pe...   EPISODE 2 LINK:    • 9th Maths | Ch 6, Ep2: Measuring Space: Pe...   EPISODE 3 LINK:    • 9th Maths | Ch 6, Ep3: Measuring Space: Pe...   EPISODE 4 LINK:    • 9th Maths | Ch 6, Ep4: Measuring Space: Pe...   EPISODE 5 LINK:    • 9th Maths | Ch 6, Ep5: Measuring Space: Pe...   EPISODE 6 LINK:    • 9th Maths | Ch 6, Ep6: Measuring Space: Pe...   EPISODE 7 LINK:    • 9th Maths | Ch6, Ep7: Measuring Space: Per...   EPISODE 9 LINK:    • 9th Maths | Ch6, Ep9: Measuring Space: Per...   DISCLAIMER: Under no circumstances will Beyond The Notz (hereafter BTN) be responsible or liable in any way for any content, including but not limited to, any errors or omissions in the content, or for any loss or damage of any kind incurred as a result of any content communicated on this youtube content, whether by BTN or a third party.
