Answer:
5cm = r
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
78.5 = 3.14 r^2
Divide each side by 3.14
78.5/ 3.14 = r^2
25 = r^2
Take the square root of each side
sqrt(25) = sqrt(r^2)
5 = r
Answer:
y-intercept is y= -4.5+28 slope is 4.5
Step-by-step explanation:
18x+4y=112
-18x -18x
4y=112-18x
-----------------
4
y= -4.5x+28
Positive square root of 0.25 = 0.5
