Question

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

Answer 1

Answer:

Length of a pencil = 18cm

And radius = 4cm

Diameter = 2 x radius

                = 2 x 4

                = 8cm

Therefore, Ratio of length to diameter = $\frac{18}{8}$

Cut $\frac{18}{8}$ with 2

And after cutting $\frac{18}{8}$ it comes $\frac{9}{4}$

Hence, The answer is 9:4

Step-by-step explanation:

Hope it helps!

Answer 2

Answer:

length of pencil (l) = 18cm

Radius(R) =4cm

Diameter =2×radius

= 2×4

= 8

Ratio of length to diameter = 18/8

= 9/4

therefore,

it's ratio is 9:4
