Question

circumference of circle whose diameter is 5.6 cm

Answer 1

Diameter = 5.6
radius = d/2 = 5.6/2 = 2.8cm
Circumference of a circle = 2πr = 2×22/7×2.8=17.6cm

Answer 2

$here \: is \: ur \: answer$

Question,

Find the circumference(in cm) of a circle whose diameter is 5.6 m.

Answer,

1760 cm

Given,

Diameter=5.6 m

To find,

Circumference of that circle

Explanation,

• Diameter-5.6,Radius-2.8

Circumference=2πr

=2π×(2.8)

$2 \times \frac{22}{7} \times 2.8$

=>17.6 m

Hence,the answer is 1760 cm.
