Question

find the circumference of the circle d=56m​

Answer 1

$\LARGE{ \underline{\underline{ \pink{ \bf{ANSWER}}}}}$

Circumference = 176m

Step-by-step explanation:

We know that circumference of circle = 2πr

Here the Given diameter = 56m

So, radius = 1/2 of the diameter

Radius = 1/2 × 56 = 28m

Let π be = 22/7

So, Circumference = 2πr

Circumference = 2 × 22/7 × 28 = 176 m

Answer 2

Answer :

›»› The Circumference of the circle is 176 m.

Given :

• Diameter of the circle = 56 m.

To Find :

• The circumference of the circle = ?

How to solve?

Here in this question we have to find the Circumference of the circle. So, firstly we need to find the radius of the circle after that we will find the Circumference of the circle on the basis of conditions given above.

To find the radius of the circle, divide the diameter value by 2.

Solution :

==> Diameter = 56 m.

==> Radius = Diameter ÷ 2

==> Radius = 56 ÷ 2

==> Radius = 28 m.

According to the given question,

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\qbezier(2.3,0)(2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,-2.121)(0,-2.3)\qbezier(2.3,0)(2.121,-2.121)(-0,-2.3)\put(0,0){\line(1,0){2.3}}\put(0.5,0.3){\bf\large 28 \ m}\end{picture}$

To find the Area of surface area of cone, we use the formula:-

❰ Circumference of circle = 2πr ❱

• π = 22/7.
• Radius = 28 m.

On putting the given values in the formula, we get

⟶ Circumference = 2 × 22/7 × 28

⟶ Circumference = 2 × 22 × 4

⟶ Circumference = 44 × 4

⟶ Circumference = 176

Hence, the circumference of the circle is 176 m.
