Answer:
radius = 21
circumference = 138.88
Step-by-step explanation:
First divide the area by 3.14, this equal 441
441 is your radius squared.
Then you have to find the root of 441 which is 21.
radius = 21
diameter = twice the radius or 2 * radius
diameter = 21 * 2 = 42
diameter = 42
Then plug 42 in your circumference formula.
Which is then C = 3.14(42).
Which means the circumference is 131.88.
Step-by-step explanation:
C. y= -5x + 27
D. y=2x - 15
thats all
