Question

perimeter of circle with diameter of 8 cm

Answer 1

Answer:

Perimeter of circle = 2πr

• Diameter = 8 = 8/2 = 4cm (radius)

Perimeter = 2×22/7×4

= 44/7= 176/4

= 25.14

Answer 2

Here the diameter of the circle is given to be 8 cm

So, radius = diameter/2

                = 8/2

               = 4 cm

We have to find the perimeter of the circle

Perimeter of the circle is its circumference

so, circumference of circle = 2πr

                                           = 2 × (22/7) × 4

                                           = 25.142 cm

Hence, the perimeter of the given circle will be 25.142 cm
