Question 4 part one is wrong correct answer is 28.5

formula is r2 (pi*theta/360 -1/2* sin theta)

[simarpreetkaur]

in question number 4 u forgot to divide 114/4 which gives us 28.5 cm^2

Sir 5 th ke first me calculation mostake h 22 aayega

[anantbrawlstarsyt]

simpler solution for q5(iii) (and basically many more questions where centre angle is 60)-
angle AOB = 60
other 2 angles will also be 60 (angle opposite to equal sides)
as all angles are 60 degree, AOB is an equilateral triangle (now you can use the formula for area of equilateral triangle(root3\4 side square) if needed to find segment for any question)
hence ab = 21cm
hope it helped😊

sir, you did the 5th question wrong i think in a hurry....that have to be 1/6 . however, we can take rt3/4* side^2 for the same in the 3rd part . anyways thanks a bunch, this video helped me a lot

[nazmeenkhan]

Sir apne 5 me shayd 90 consider krliya angle

[TRACTOR._.MODIFIED]

Simple solution for finding angle of triangle is 1/2 × product of adjacent sides × sinΩ(theta)

"Pause the video to note it down"❤️❤️
Sir you explained this exercise in very easy way. thank you so much sir😊😊

[poojakori]

thankyou so much for explaining in this much
