Question

A cylinder has a height of 5.3 cm and a diameter of 3.0 cm. What is its volume? (Hint: Volume of a cylinder = r2h ) 25.0 cm3 66.2 cm3 149.9 cm3 37.5 cm3

Answer 1

Answer:

37.5 cm³ .

Step-by-step explanation:

h = 5.3 cm

diameter = 3 cm

r = 3/2 = 1.5 cm

Volume of cylinder = πr²h   {Plug in the values of h & r }

                               = 3.1428 * 1.5 * 1.5 * 5.3

                               = 37.5399

                               = 37.5 cm³

Answer 2

Answer:

37.5cm3

Step-by-step explanation:

Diameter = 3cm

Radius = 3cm÷2

= 1.5cm

Volume of cylinder= πr²h

= π(1.5²)+5.3

= 37.5 (3 S.F.)
