Given the area of a circle is 201.06cm2, find the diameter and circumference.

D=   15.9999299716 meters

C= 100.530524913 cm.

Step-by-step explanation:

1. Find the diameter

Divide the area (in square units) by Pi (approximately 3.14159).

201.06/3.14159 = 63.9994397741

Take the square root of the result 7.9999649858. This is the radius.

Now double the radius to get the diameter. 15.9999299716 meters

2. Find the circumference

C = 2 * π * R = 2 * π *  15.9999299716 = 100.530524913 cm.

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
