Volume and surface area are 324.99 cm² and 273.18 cm².
Given - Diameter and height
Find - Volume and surface area
Solution - Volume = πr²h
Radius = diameter/2
Radius = 6/2
Radius = 3 cm
Keep the values in formula
Volume = 3.14*3²*11.5
Volume = 324.99 cm³
Surface area = 2πrh + 2πr²
Surface area = 2*3.14*3*11.5 + 2*3.14*3²
Surface area = 216.66 + 56.52
Surface area = 273.18 cm²
Hence, (a) volume is 324.99 cm² and (b) surface area is 273.18 cm².
