Question

6.
The radius of a cylinder is 8 cm and its height
is 7 cm. Find the curved surface area and total
surface area of the cylinder.
​

Answer 1

Answer:

Given-

1. r=8cm
2. h=7cm

Solution-

• Curved surface area of cylinder=2πrh
• Curvedsurface area of cylinder=2×(22×7)×8cm×7cm
• =352cm²
• Total surface area of cylinder=2πr(h+r)
• Total surface area of cylinder=2×(22/7)×8cm(7cm+8cm)
• =754.28cm²
