Step-by-step explanation:
The length of the arc is calculated as
AB = circumference of circle × fraction of circle
(11)
AB = 2πr × 
= 2π × 7 × 
= 14π × 
=
π in
(12)
AB = 2πr ×
( r = 20 ÷ 2 = 10 )
= 2π × 10 × 
= 20π × 
=
π
=
π cm
It’s 60 miles an hour rate
Answer:
2x + 6
2 times the number x is 2x (2 times x)
six more than that would be +6
A ratio has to be equal to what is given, in this case, 5/45. 5 divided by 5 is 1 and 45 divided by 5 is 9. So one answer is 1/9.
I think the length is ten
