Question

The length of a pencl is 18cm and its radius is 4cm. Find the ratio of its length to its diameter.

Answer 1

Answer:

9 : 4

Step-by-step explanation:

We must first list all the information that is provided to us,

Length of pencil = 18 cm

Radius of pencil = 4 cm

We know that the diameters for all circles is the double of their respective radii.

Hence, Diameter of the pencil = 2 * 4 = 8 cm

Now, required ratio will be as follows,

Length of pencil / Diameter of pencil

$\frac{18}{8} \\ \\ \frac{9}{4}$

=> 9 : 4
