Given:
- Height of cylinder is 18.2 cm
- Radius of cylinder is 3 cm
![~](https://tex.z-dn.net/?f=~)
To Find?
![~](https://tex.z-dn.net/?f=~)
Solution:
Using formula:
- Surface area of cylinder = 2πr (h + r)
![~](https://tex.z-dn.net/?f=~)
Substituting values in the formula:
![\longrightarrow \sf 2 × 3.14 × 3 (18.2 + 3)](https://tex.z-dn.net/?f=%5Clongrightarrow%20%5Csf%202%20%C3%97%203.14%20%C3%97%203%20%2818.2%20%2B%203%29%20)
![\longrightarrow \sf 6.28 × 3 (21.2)](https://tex.z-dn.net/?f=%5Clongrightarrow%20%5Csf%206.28%20%C3%97%203%20%2821.2%29)
![\longrightarrow \sf 18.84 × 21.2](https://tex.z-dn.net/?f=%5Clongrightarrow%20%5Csf%2018.84%20%C3%97%2021.2)
![\longrightarrow \sf 399.4 cm²](https://tex.z-dn.net/?f=%5Clongrightarrow%20%5Csf%20399.4%20cm%C2%B2)

The answer is 14
Step-by-step explanation:
140 is a composite number. Factor pairs: 140 = 1 x 140, 2 x 70, 4 x 35, 5 x 28, 7 x 20, 10 x 14. Factors of 140: 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140. Prime factorization: 140 = 2 x 2 x 5 x 7, which can also be written 140 = 2² x 5 x 7
