Answer:
≈ 18.8 cm
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
The central angle is equal to the arc subtending it, that is 60°
arc = 2πr ×
= 2π × 18 ×
= 36π ×
= 6π ≈ 18.8 cm ( to 1 dec. place )

I have made it in above picture
Answer:
Step-by-step explanation:
The equation which can convert the temperature from degree Celsius into degree Fahrenheit is given as under
We can solve it further for F as
Dividing both sides by 5 we get
Now substituting values of C in this equation will give us the corresponding values of F
Ex : C=1
Hence 1 degree Celsius is degree Fahrenheit
