Question

The following is a table of values connecting the radii of a
few circles and their circumferences (Taking n = 22)
Illustrate the relation with a graph and find
(1) The radius when the circumference is 242 units.
(ii) The circumference when the radius is 24.5 units.​

Answer 1

can you please send correct information I can't understand. sorry

Answer 2

1) The radius of a circle $= 78.5 units$

2) The circumference of a circle = 154 units

Step-by-step explanation:

Given,

 $\pi =\frac{22}{7}$

To find, 1) radius (r) = ?

2) The circumference = ?

1) Given, the circumference of a circle = 242 units

We know that ,

The circumference of a circle = $2\pi r$

⇒  $2\times\frac{22}{7} \times r=242$

⇒ $2\times\frac{1}{7} \times r=11$

⇒ $r=\dfrac{77}{2} = 78.5$ units

2) Given, the radius of a circle = 24.5 units

We know that ,

The circumference of a circle = $2\pi r$

$=2\times\frac{22}{7} \times 24.5$

$=\dfrac{1078}{7} =154$ units
