Answer:
the radius must equal 2
Step-by-step explanation:
A = pi * r^2 C = 2 * pi *r
set them equal
pi * r^2 = 2 * pi *r
divide both sides by pi
r^2 = 2 * r
divide both sides by r
r^2 /r = 2r/r
r = 2
Answer:
y=6.2 and x=0.4 or (0.4,6.2)
Step-by-step explanation:
Since both expressions are equal to y, we can set them equal to each other and solve for x:
3x+5=8x+3
5=5x+3
2=5x
2/5=x
0.4=x
Now to solve y:
y=8(2/5)+3
y=16/5+3
y=3.2+3
y=6.2
Check answers:
6.2=3(0.4)+5
6.2=1.2+5
6.2=6.2
6.2=8(0.4)+3
6.2=3.2+3
6.2=6.2
Answers work, so y=6.2 and x=0.4 or (0.4,6.2) as an ordered pair
All you have to do is 14*.30 which equals to $4.20
