Question

If a radius of a wheel is `14cm`.Find its diameter and circumference. please i want solving also not only answer​

Answer 1

Answer:

If the radius of the wheel is 14 cm, then the diameter of the wheel is 28 cm and the circumference of the wheel is 88 cm.

Step-by-step explanation:

Given: Radius of wheel = 14 cm

π = 22/7

Find the diameter of circle  and circumference of a circle

Step 1: Find the diameter of the circle

The diameter of circle = 2 × r = 2 × 14 = 28 cm

Step 2: Find the circumference of the circle = 2 × π × r

= 2 × 22/7 × 14

= 2 × 22 × 2

= 88 cm

So, the diameter of the circle is 28 cm and the circumference of the circle is 88 cm.

Answer 2

Answer:

Therefore the value of circumference is 88cm.

Step-by-step explanation:

As per the data provided in the given question

The given data is as follows,

A Radius of the wheel i.e.(r) is 14cm.

We have to find the value of diameter and circumference.

We know that diameter of the circle is 2 times of radius.

So,

$d=2\times r$

$d=2\times14\\d=28cm$

Now we will find the value of circumference.

Here, we will be using the formula of circumference.

$Circumference=2\pi r$

We will substitute the given values in the above formula.

$=2\times\frac{22}{7}\times14$

Now we will divide 14 by 7 we get

$=2\times22\times2\\=2\times2\times22\\=4\times22\\=88cm$    

Therefore the value of circumference is 88cm.
