Therefore radius of circle one,
Therefore radius of circle two,
Answer:
Formula for circumference of a circle
2\pi \: r2πr
Circumference of circle 1 = 44cm
\begin{gathered}2\pi \: r = 44cm \\ = \pi \: r = 22cm \\ \frac{22}{7} \times r = 22cm \\ = r = 7cm\end{gathered}
2πr=44cm
=πr=22cm

22
×r=22cm
=r=7cm
Circumference of circle 2 = 110cm
\begin{gathered}2\pi \: r = 110cm \\ = \pi \: r = 55cm \\ = \frac{22}{7} \times r = 55cm \\ = \frac{2}{7} \times r = 5cm \\ = r = 17.5cm\end{gathered}
2πr=110cm
=πr=55cm
=
×r=55cm
2
×r=5cm
=r=17.5cm
Difference between the two radii,
\begin{gathered}(17.5 - 7)cm \\ = 10.5cm\end{gathered}
(17.5−7)cm
=10.5cm
Step-by-step explanation:
Hope this answer will help you dear...
