Answer:
The circumference is 28.27in.
The circumference of the circle is 28.26 in.
Step-by-step explanation:
Given,
The diameter of a circle = 9 in
Radius of the circle (r) = 4.5 in
To find the circumference of the circle.
Formula
The circumference of the circle of radius r = 2πr
Now,
The circumference of the circle = 2×3.14×4.5 in [ taking π = 3.14]
= 28.26 in
5x +4(2y) = 50
i can only think of this but i have no idea if it's correct
Answer: -x/2 + 1
write t in terms of x
x = 2t
t = x/2
substitute t in y
y = 1 - t
y = 1 - x/2 or -x/2 + 1
400mL/3l
Is the correct answer
