Question

write all the formulas that can be used in the chapter named surface areas and volumes

Answer 1

✴hy✴
✴here is your answer ✴
======================
1. surface area of a cuboid=2(lb+bh+hl)

2. surface area of a cube=6a²

3. curved surface area of a cylinder=2πrh

4. total surface area of a cylinder=2πr(r+h)

5. curved surface area of a cone=πrl

6. total surface area of a right circular cone=πr(l+r)

7. surface area of a sphere of radius=4πr²

8. curved surface area of a hemisphere=2πr²

9. total surface area of hemisphere=3πr²

10. volume of a cuboid=l×b×h

11. volume of a cube= a³

12. volume of a cylinder=πr²h

13. volume of a cone=1/3πr²h

14. volume of a sphere of radius=4/3πr³

15. volume of a hemisphere=2/3πr³

I hope you understand

Answer 2

cube:
tsa-6a sq
csa- 4a sq
volume-a cu

cuboid:
TSA- 2(lb+bh+hl)
CSA- 2(l+b)h
volume-lbh

cone:
CSA- πrl
tsa - 2 πr(r+l)
volume- 1/3 πr2 h
