Given,

Diameter = 2.5 m

radius = $\frac{2.5}{2}$

= 1.25 m

therefore, Circumference = 2 π r

= (2 × 3.14 × 1.25)m

= 7.85 m

Answer 2

Answer:

The circumference of the circle is 7.85 m.

Step-by-step explanation:

In the question, the diameter of the circle is given as 2.5m and we need to find the circumference of that circle. So, if the diameter of the circle is 2.5 m, or, 25/10 m, its radius will be the half of the diameter, ie, 25/20 m. Also, its mentioned that we have to take the value of pie (π) as 3.14, not 22/7. So lets start.

We have the radius as 25/20 m and we have to find the circumference. We know that the circumference of a circle is given by the formula 2πr, where r is 25/20 m or 5/4 m and the value of π is 3.14 or 314/100. So, the circumference of the circle is as below:

2πr = (2 × 314 × 5) ÷ (100 × 4) = 3140 ÷ 400 = 785 ÷ 100 = 7.85 meters

Thus, the circumference of the circle is 7.85 m.
