Tomtit [17]

Answer:

The volume is about 4.24 cm^3.

Step-by-step explanation:

From the question we are told that:

Diameter $d= 3-cm$

Radius $r=d/2=>1.5cm$

Height risen $14.6-14=0.6cm$

Generally the equation for Volume of a Key is mathematically given by

Since Volume of a cylinder is Given as

$V=\pir^2h$

Therefore

$V=\pi*1.5^2*0.6$

$V=4.2417\\\\V=4.24 cm^3$

Correct Option A

The volume is about 4.24 cm^3.
