Question

find the diameter of the circle who circumference is 2.2cm​

Answer 1

Step-by-step explanation:

Circumference = 2πr

\begin{gathered}2 \times \frac{22}{7} \times r = 2.2cm \\ r = \frac{2.2cm \times 7}{2 \times 22} \\ r = 0.35cm\end{gathered}

2× 722

×r=2.2cmr= 2×22

2.2cm×7

r=0.35cm

Answer 2

Answer:

let the radius be x

circumference=2πr=2.2cm

a/q 2*22/7*x=2.2cm

44x/7=2.2cm

44x=2.2cm*7

44x=22/10*7

44x=154

x=154/44=6mm
