Answer:
18.8
Step-by-step explanation:
multiply pi by the diameter (6 cm) and you get the circumference
hope that helps
Answer:
Step-by-step explanation:
Be sure to insert π where appropriate!
If the diameter of the yo-yo is 4 in, then the radius is 2 in.
The area comes from A = πr² and the circumference from C = πd.
In this case the area is A = π(2 in)² = 4π in² or 12.57 in².
The circumference is C = 4π in or 12.57 in.
Answer:
<FJB = 112°
Step-by-step explanation:
Sum of 3 angles in a triangle = 180
Given:
<FBJ = 32°
<BFJ = 36°
so
<FBJ + <BFJ + <FJB = 180°
32° + 36° + <FJB = 180°
<FJB + 68° = 180°
<FJB = 180° - 68°
<FJB = 112°
Answer:
(2,5)
or x=2, y=5
Step-by-step explanation:
3x+2y=16
substitute y =x+3 every place you see a y
3x + 2(x+3) = 16
distribute
3x + 2x +6 = 16
combine like terms
5x+6 = 16
subtract 6 from each side
5x+6 -6 =16-6
5x =10
divide by 5
5x/5 = 10/5
x = 2
now we need to find y
y = x+3
y = 2+3
y=5
(2,5)
or x=2, y=5
