Answer 2

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.
