Final answer:
The equation that can be used to find the volume of the cylinder with a diameter of 6cm and a height of 14cm is V = πr²h. The volume can be calculated by plugging in the values and solving. In this case, the volume is 126π cm³.
Step-by-step explanation:
The equation that can be used to find the volume of the cylinder with a diameter of 6cm and a height of 14cm is:
V = πr²h
First, we need to find the radius of the cylinder. The radius is half of the diameter, so the radius is 6cm/2 = 3cm.
Plugging in the values, we get:
V = π(3cm)²(14cm)
V = 9π(14cm)
V = 126π cm³
