Question

what will be the circumference of a circular plate whose radius is 28 cm​

Answer 1

Answer:

Circumference of the circular plate = 176 m

Step-by-step explanation:

Circumference = $\sf 2\pi r$

Circumference = $\sf 2\times \dfrac{22}{7} \times 28$

Circumference = $\sf 2\times \dfrac{22}{\cancel{7}} \times \cancel{28}$

$\therefore$Circumference = 2 × 22 × 4 = 176cm

Answer 2

$\bf\green{QuestioN:-}$

What will be the circumference of a circular plate whose radius is 28 cm​  ?

$\bf\red{AnsweR:-}$

Given :

Radius of the circular plate = 28 cm

To Find :

Circumference of that circular plate.

Solution :

As we know,

Circumference of a circle = 2πr.

Here,

Radius = 28 cm.

The apprx value of π = 22/7

Circumference = 2πr

$\longrightarrow\bf{2\times\dfrac{22}{7}\times28}$

$\longrightarrow\bf{2\times22\times4=176}$

The circumference of the circular plate = 176 cm.

All Done !!☺
