Answer:
Curved surface area of cylinder =
2πrh.
= 2 × 22/7 × 7 × 10 = 440 cm^2
total surface area of cylinder = 2πr(h + r) = 2 ×22/7 × 7 ( 7 + 10 ) = 748cm^2

Step-by-step explanation:
Given : The radius of a circular cylinder is 7 cm, its height is 10 cm.
To find : The curved surface area, total surface area and volume of the cylinder ?
Solution :
The radius is r=7 cm
The height is h=10 cm
curved surface area of the cylinder= 2πrh
= 2× 22/7×7×10cm^2 = 440cm^2
total surface area of the cylinder= 2πr( r+h)
= 2×22/7×7 (7+10)cm^2
= 44 ×17 cm^2= 748cm^2.
