Step-by-step explanation:
The diameter is 28 so 28/2=14cm
The height is 15cm
So the formula is 2*22/7*14*15
So the answer is 1320
Hope this will help you
Thank you
Given : cylinder
diameter of the base is 28 cm and height is 15cm.
To Find : curved surface area
Solution:
curved surface area of cylinder = 2πRh
R = Radius = Diameter /2 = 28/2 = 14 cm
h = Height = 15 cm
π = 22/7
curved surface area of cylinder = 2 (22/7) 14 * 15
= 44 * 2 * 15
= 44 * 30
= 1320 cm²
curved surface area of the cylinder = 1320 cm²
