Solution :
Given that :
The radius of circle A = 6 cm
The radius of circle C = 4 cm
In circle A

The length of arc EF = 

= 14.653 cm
In circle C

The length of arc GH = 

= 9.769 cm
Therefore,
The length of EF is 14.653 cm
The length of GH is 9.769 cm
The length of EF is 1.5 times the length of GH
i.e. 14.653 = 1.5 x 9.769
14.653 = 14.653
Hence proved.

Really bad according to the BLS, the average secondary school teacher in the U.S. earns an annual salary of $56,760. A 40-hour work week employee would have to earn $27.28 per hour to earn as much over the course of a year.
If we multiply and then divide the number by the same thing,
we won't change its value.
Take the number: 58,000,000,000
Divide it by 10¹⁰ : 5.8
Multiply it by 10¹⁰ : 5.8 x 10¹⁰
They want a single digit, so we'll round the 5.8
to the nearest whole number:
6 x 10¹⁰ .
