Question

Find circumstance of stadium , if it's diameter is 2.5km. Express the Answer in meters {π=3.14}​

Answer 1

Circumference = 2×pie×r

= 2r × pie = 2500 × 3.14

(as d = 2r and 2.5km = 2500m )

= 7850m

Answer 2

Circumstance Of Stadium is 7850 meters

Step-by-step explanation:

GIVEN

Diameter = 2.5 km

π = 3.14

___________________________

TO FIND

Circumstance Of Stadium

___________________________

We know that,

1 km = 1000 m

2.5 km = 2500 m

Diameter = 2500 meters

___________________________

We know that,

Diameter = 2 × Radius

Radius = Diameter / 2

Radius = 2500 / 2

Radius = 1250

Radius = 1250 meters

___________________________

We know that,

Circumstance Of Stadium = 2 × π × r

Circumstance Of Stadium = 2 × 3.14 × 1250

Circumstance Of Stadium = 6.28 × 1250

Circumstance Of Stadium = 7850

Circumstance Of Stadium = 7850 meters

Circumstance Of Stadium is 7850 meters
