Answer:

Diameter of circle is 20.3\ m .

Step-by-step explanation:

To find : diameter of circle .

Given : circumference is 63.8 m.

Solution :

  • As per given that we know that circumference of circle is 63.8\ m .We are asked to find diameter of circle.
  • We use following formula to find circumference of circle, using this formula we find find radius of circle by substituting the given values.
  • Circumference of circle = 2\pi r  

       63.8 = 2\times\frac{22}{7}\times r \\r = \frac{63.8 \times 7}{2\times 22}   \\r = 10.15

  • Now, as we know that diameter is twice of radius, therefore we write as

       $\begin{aligned} \text { Diameter } &=2 r \\ &=2 \times 10.15 \\ &= 20.3\mathrm{~m} \end{aligned}$

Circumference of a given circle is 63.8m

∴C=63.8m

Let the radius of the given circle be r m

Then,

C=2πrunits

r=(31.9×0.3182)

r=10.15m

∴ Diameter of the circle =2r=(2×10.15)=20.3cm
