Answer:
4
Step-by-step explanation:
circumference = 2πr
or, 20 = 2π r
or, π r = 10
or, r= 10/π
72 ° = 2π/5
length of arc = r∅ = 10/π × 2π/5
= 4

Your Answer Is $7.50 Because 3/4 Of $10 Is $7.50
The list of pairs of integers will be created by starting with the factor pairs for 30.
1 x 30
2 x 15
3 x 10
5 x 6
Then multiply these with negative integers which will result in a positive answer.
-1 x -30 (This means the opposite of one groups of negative 30, which is posiitve 30).
-2 x -15
-3 x -10
-5 x -6
When you have two fractions equal to each other, you can cross multiply. So, multiply x by 5 and 4 by 15.
5x = 60
Divide both sides by 5.
x = 12.
