Answer 2

Answer:

308mm³

Step-by-step explanation:

Height of the coin = 2mm

Diameter of the coin = 1.4 cm

∴ Radius of the coin = 0.7cm = 7mm

Formula of the volume of a cylinder =  πr²h

                                                            = $\frac{22}{7}$ × 7² × 2

                                                            = 22 × 7 × 2

                                                            = 308mm³

Hope that helps you...☺
