Answer 2

Answer:

Concept: A Stadium is a round circle who has a diameter and a radius which is half of a diameter.

Given: Diameter is 2.5 km. And π=3.14

To find: the circumference of the stadium in meter.

Step-by-step explanation:

As we know that a circle has a radius which is half of a diameter.

so we can say that radius of the stadium is $\frac{2.5}{2}km$ which is $1.25km$ .

however , circumference of a circle is 2πr.(given π=3.14)

so , if we put that values in the above formulae , we will get

circumference of the stadium = $2*3.14*1.25$

so , circumference of the stadium is $7.85 km$.

and to express in meter, we can say that circumference is $7.85*1000 m$

which is $7850m$ .

therefore, circumference of the stadium is 7850 m
