Find the the total surface area, curved surface area and volume of a cylinder whose radius is 7 cm and height 10 cm
Answers
✯ TSA = 748 cm² ✯
✯ CSA = 440 cm² ✯
✯ Volume = 1540 cm³ ✯
Step-by-step explanation:
Given:
- Radius of the cylinder = 7 cm
- Height of the cylinder = 10 cm
To find:
- Total surface area (TSA)
- Curved surface area (CSA)
- Volume
Solution:
- Radius (r) = 7 cm
- Height (h) = 10 cm
We know that,
✯ TSA of cylinder = 2πr (h+r) ✯
Then,
Total surface area of cylinder,
= 2×(22/7)×7(10+7) cm²
= 2 × 22 × 17 cm²
= 748 cm²
Therefore the total surface area of the cylinder is 748 cm².

We know that,
✯ CSA of cylinder = 2πrh ✯
Curved surface area of cylinder,
= 2×(22/7)×7×10 cm²
= 2×22×10 cm²
= 440 cm²
Therefore, the curved surface area of the cylinder is 440 cm².

We know that,
✯ Volume of cylinder = πr²h ✯
Volume of cylinder,
= (22/7)×7×7×10 cm³
= 22×7×10 cm³
= 1540 cm³
Therefore, the volume of the cylinder is 1540 cm³.

Answer:
given
radius-7 cm , height-10 cm
total surface area area of cylinder is 2πr(r+h)
= 2×22\7×7(7+10).
=352cm
curved surface area of cylinder= 2πrh
= 2×22\7×7×10
=440cm
Volume of a cylinder = πr²h
22\7×7×7×10
154cm²
