Question

find the radius and diameter of a circle whose circumference is 5.5 km​

Answer 1

Answer:

1.75 km

Step-by-step explanation:

Diameter of circle = 2 × Radius

∴ Hence, Diameter of circle is 1.75 km

Answer 2

• As per the data given in the question, we have to find the value of the expression.

           Given data:- circle whose circumference is $5.5km.$

           To find:- The value of the given expression.

           Solution:-

• There are three properties of circle namely,

1. radius
2. diameter
3. circumference

• The radius of a circle

             $C=2\pi r\\r=\frac{c}{2\pi } \\r=\frac{5.5}{6.2831} \\r=0.8753.$

      Hence the circle of radius is $0.8753.$

• The Diameter of a circle

          $d=2\times r\\d=2\times 0.8753\\d=1.75.$

    Hence the circle of diameter is$1.75.$
