The area of a circle is given by A=Pi*r^2, and its perimeter, P=2*Pi*r.
To get the radius r, you must divide 452.2 by Pi, and then calculate the square root of this quotient.
To get the circumference or perimeter, use the radius in the formula P=2*Pi*r.
Finally, round the number you get to the nearest tenth.
Answer:
C = 18.85
Step-by-step explanation:
The formula for the circumference of a circle is C = 2πr
R = radius
C = 2π(3)
C = 18.84955592
2(3-4)+3(3)-(3)^2
2(-1)+3(3)-9
-2+9-9
7-9
-2
Well, since opposite sides of a parrallelogram add up to 180 degrees, by subtracting 53 from 180, you get x=127 degrees.
