Given:
A cylindrical container closed of both end has a radius of 7cm and height of 6cm.
Explanation:
A.) Find the total surface area of the container.
- A = 2πrh + 2πr²
- A = 2(3.14)(7)(6) + 2(3.14)(7 × 7)
- A = 263.76 + 307.72
- A = 571.48
B.) Find the volume of the container.
- V = πr²h
- V = (3.14)(7×7)(6)
- V = 923.16

Answer: TSA = 572 cm^2
Volume = 924 cm^3
TSA of a cylinder = 2πr^2+2πrh
= 2πr(r+h)
= 2×22/7×7(7+6)
= 44×13
= 572 cm^2
Volume of the container= V = πr^2 h
= 22/7 * 7*7 * 6
= 924 cm^3
