Question

What is the circumference of the pizza whose diameter is 30 cm with full answer ​

Answer 1

Answer:

Circumference of pizza= 94.2$cm^{2}$

Step-by-step explanation:

According to the information provided in the question it is given as

Diameter =30 cm

We need to find the circumference of the pizza

Here it is given as that pizza is in the shape of circle before finding the circumference first understand the meaning circumference

The circumference of a circle, place, or round object is the distance Around its edge

The distance around the edge of a circle (or any curvy shape). It is a type of perimeter.

Circumference of circle = 2$\pi r$

Here diameter is given as d =30 cm

                                            r = d/2

                                            r = 30/2

                                            r= 15 cm

[tex]Circumference = 2\pi r\\ C= 2\times \frac{22}{7} \times 15[/tex]

[tex]C = 2\times 3.14 \times 15\\ C= 94.2cm^{2} [/tex]

Hence circumference of circle that is the circumference of pizza is

94.2$cm^{2}$

                                 

Answer 2

Question:-

what is the circumference of the pizza whose diameter is 30 cm.

Given:-

• diameter of pizza = 30 cm

To Find:-

• The circumference of the pizza.

Solution:-

Formula Used:

${ \boxed{ \sf \large \color{red}Circumference \: of \: a \: circle = 2\pi r.}}$

π is the numerical constant with an approximate value of 3.14156.

2πr = (2r) × π = 3.14156 × 30

Thus, the circumference of the pizza = 94.2486 = 94.25 (after rounding off to two decimal places).

Answer:-

${ \boxed{ \sf \large \color{red}Hence, the \: circumference \: of \: the \: pizza \: is \: 94.25 \: cm².}}$

More Information:-

The diameter of a circle is given by joining any two points on the circle such that the line passes through the center. In other words, the diameter of a circle is twice its radius i.e., 2r.

Hope you have satisfied. ⚘
