A container with:
<h3>
To find</h3>
- The radius of the container
<h3>Solution</h3>
Use the equation for total surface area of cylinder:
- S = 2πr² + 2πrh or S = 2πr(r + h)
Since we have r = h and the value of S is known, let's solve this equation:
- 2πr(r + h) = 300
- 2πr(r + r) = 300
- 2πr(2r) = 300
- 4πr² = 300
- πr² = 75
- 3.14r² = 75
- r² = 75/3.14
- r² = 23.89 (rounded)
- r = √23.89
- r = 4.89 cm (rounded)
Prime numbers mean that their factors are only the number itself and 1.
2, 3, 5, 7, 11, etc. all fall under this category.
note however, that the numbers have to be less than 8: [2, 3, 5, 7] are your choices
2 + 3 = 5
5 + 5 = 10
10 + 7 = 17
Therefore, {2, 3, 5, 7} are your answers
hope this helps
