Given: Circumference of base of cylinder = 25.45 cm
Height of cylinder, h = 15 cm
To find: Curved Surface Area (CSA)
Explanation:
Since the base of any cylinder is a circle and the circumference of a circle is given by 2πr, where r = radius of circle / base of cylinder
Therefore, 2πr = 25.45cm
r = 25.45/(2×3.14) (π=3.14)
r = 4.05cm
Curved Surface Area of a cylinder = 2πrh
= 2×3.14×4.05×15
= 381.51 cm
Thus, the curved surface area of the cylinder is 381.51 cm.
