1:03:28 ₹210=100m² 1m²=₹2.1 CSA of cone =πrl ◆22/7×7×25= 550m². COST OF WHITE WASK FOR 550m² = 550×2.1 =₹1155
@God_memer66
1:12:13 Volume of cone =1/3πr²h 18480=1/3×22/7×r²×40 18480×3×7/22×7=r2 147×3=r² 441=r² √441=r 21cm=r

The most awaited chapter comes❤❤❤❤❤❤❤❤❤❤❤
@Trishaguptamallick
1:05:07 As area of circle is πr² πr²=314 3.14×r²=314cm(takingπvalue=3.14) r²=314/3.14=100 r²=100, r=√100=10 Volume of cone=1/3πr²h 1/3×3.14×10×10×15 1×314×5=1570cm³(ANS) THANKYOU😊
@samiyakhan1636
1:05:01 Volume of cone:1/3πr²h =1/3×314×15 =1570cm³
@sangeetasingh750
57:27 sir you have mistaken here. You wrote 4 instead of 14.
@RespectForAnimal
1:03:38 Answer is Rupees 1155. AM I CORRECT?
@harshgoyal.5368
43:36 this is very important
@sushmaambashth9600
1:06:13 1/3×314×15 so here we can simplify 3 &15 so 15 will get cut & will be 5 so 314×5=1570cm²
