Question

Jonathan wants to buy a lid for his frying pan. The diameter of the pan is 11 inches. What is the approximate circumference of a lid that will fit his frying

Answer 1

the approximate circumference of a lid that will fit his frying is 34.5 inches .

Step-by-step explanation:

Here we have , Jonathan wants to buy a lid for his frying pan. The diameter of the pan is 11 inches. We need to find What is the approximate circumference of a lid that will fit his frying . Let's find out:

We know that  a lid for his frying pan is basically in shape of circle , So we consider a lid for his frying pan as a circle ! Now ,

Circumference of circle = $2\pi r$ , r = radius

⇒ $Circumference =2\pi r$

⇒ $Circumference =2\pi \frac{D}{2}$

⇒ $Circumference =\pi D$ , D = Diameter = 11 inches

⇒ $Circumference =\pi (11)$

⇒ $Circumference =(3.14) (11)$

⇒ $Circumference =34.5inches$

Therefore , the approximate circumference of a lid that will fit his frying is 34.5 inches .

Answer 2

The approximate circumference of a lid that will fit his frying pan is 34.54 inches.

Step-by-step explanation:

Let us assume that the frying pan is in the shape of circle.

This is because, from the given question it is predictable that the circumference is one of the parameter of the circle.

It is given that,

The diameter of the pan is 11 inches.

⇒ Diameter = 11 inches.

To find the radius of the lid :

Radius = diameter / 2.

⇒ 11/2

⇒ 5.5 inches.

The radius of the lid is 5 inches.

To find the circumference of the lid :

Circumference = 2πr

where,

• π has the default value of 3.14
• r is the radius of the lid.

Circumference of the lid = 2 × 3.14 × 5.5

⇒ Circumference = 34.54 inches

The approximate circumference of a lid that will fit his frying pan is 34.54 inches.
