Question

The circumference of a circle is 31.3 meters. What is the approximate length of the radius?

Answer 1

circumference of circle = 2πr

31.3= 2× 3.14× r

r= 31.3÷2×3.14

r=4.98

approximately 5...

Answer 2

The circumference of a circle is 31.3 meters. What is the approximate length of the radius?

Answer : 5 m ( approx )

Let's see the answer step by step.


Step by step explanation :

We are aware that :

Circumference of circle = 2 π r

( Here, Let's assume as π = 3.14 )

Circumference = 31.3 m ( Given )

.°. 31.3 = 2 × 3.14 × r

31.3 = 6.28 r

31.3/6.28 = r

4.98 metres = r

.°. Approximate value = 5 metres

Thus,

Final Answer :

The radius of circle = 5 metres.
