Answer: 12.56
Step-by-step explanation:
If I remember correctly, the equation for circumference is C=2r*pi (R representing radius). For this problem, if 2 is your radius 2R would equal 4. Take this number and multiply it by 3.14 (pi) to get your final answer.
Answer: 60°
Step-by-step explanation:
π/3
Since π is denoted as 180°, the question can be rewritten as:
π/3 .
To convert π/3 radians to the nearest degree will be:
π/3 = 180/3
= 60°
Answer: x=75
Explanation:
x+10+x+20=180
combine like terms
2x+30=180
subtract 30 from each side
2x=150
divide each side by 2
x=75
2x-3>11-5x
Simplify both sides of the equation
2x-3>-5x+11
Add 5x to both sides
2x-3+5x>-5x+11+5x
7x-3>11
Add 3 to both sides
7x-3+3>11+3
7x>14
Divide both sides by 7
7x/7>14/7
x>2
I hope that's help !
