[@sayyedaamir7971]

Sir Q no..1.. a cone has a base of radius 3 cm and slant height 5 cm . find its height /area

[@lichhmansingh2343]

CSA = 47.14cm² (approx)
Height= 16cm

[@learnfrombasicsshreya]

Use Pythagoras theorem
Height=4 cm
curved surface area = 47.1cm^2

Waah kitna kubsoorat hai behtreen sandaar laajawab

[@videepsutar-yv9ee]

sir videep here in the second question
we can take
22/7x12(21+12)
we can cut 7 by 21
which gets 22x12(3+12)

[@karthikniyathikaja2118]

You cant do that, its a binomial

[@gayatridhruw8623]

It will be 22 ×12×33/7

Sir please long division ke ek video banai

[@b.rudhra8409]

Sir thankyou sir for helping me for exam😊😊😊😊❤🎉

[@jeevankhansidaparvin2551]

Sir I have doubt
Question 5
Cost 100m square=rupees 210
Then 550 =x
Sir we can multiply 5 times 210 ×5 =1050
But u r saying 1155

[@radheshyammenaria6784]

We multiply210 x 5.5

[@royalgirlslifestyle1718]

No we can't divide it like that to get the right answer we must have to divide it like that:: 5 50 multiply by 210 /100 and we do it like that because it was given in the question that the cost of painting 100 square metre area we will have to give rs 210 so if we have the area of 550 so we must have to multiply it by 210 and in a pond we have to also multiply it by 100

[@guddikumari4108]

​@@radheshyammenaria67841155

[@reyyinbow07]

See, cost of 100m² =₹210
hence, cost of 1m² = 210/100 so we cancel zero and it's 21/10.
Now, cost of 550 m²=21/10×550
and 10 will cancel 550 by 55.
so 21×55=₹1155

[@Abcdefgh_lmnopqrz]

Sir but in question number 5, tarpaulin is not normal cloth that is wrapped around a cardboard/metal that can be cut according the measurements u need. It is a typical blue plastic like thick material with holes On the sides to to put tents and and other stuffs. But now we have varients in tarpuli' like canvas etc

[@Nomadsforall3209]

Sir
Ouestion number 3 - have CSA = 308 and R= 7 so
TSA = πrl+πr²
= 308 + 22/7×7²
Ans=462cm²

[@piyujolanya9818]

Yes bro😂

[@Sharpstudent8354]

My answer is also same fr

[@JDM_world.]

TSA = πr(r+l)
