Wouldn’t it be 23? 5x2 because you have to account for the top and bottom. And than the sides 6x2. 5x2=10 6x2=12. 10+12=22? I believe this is what you’re asking.

Find the height of a cone with volume 4034.66 cm^3 and radius 13 cm.

pav-90 [236]

Volume of cone=4034.66cm^3
Pi×r^2×h/3=4034.66
Pi×13×13×h=4034.66×3
22×13×13×h/7=4034.66×3
h=4034.66×3×7/13×13×22
h=45.57
So h=45.6cm

4. 795

5. 802

6. 643

7. 228

8. 479

10. 543 (10 more) gives 553. You can find out the number that is 10 more when you add the regular number by 10, 543 + 10 = 553.

Hope this helped!
