Answer:
- The radius of the container is approximately 4.89 cm
Explanation:
Given
A container with:
To find
- The radius of the container
Solution
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)
