Circle P has a circumference of approximately 75 inches.
What is the approximate length of the radius, ? Use 3.14 for
T. Round to the nearest inch.
va
12 inches
24 inches
38 inches
46 inches

The answer to your question is 12 in

Step-by-step explanation:

Data

Circumference = 75 in

radius = ?

π = 3.14

Circumference is defined as the distance around the edge of a circle.

Formula

Circumference = 2 π radius

Solve for radius

Radius = Circumference / 2π

-Substitution

Radius = 75 / 2(3.14)

-Simplification

Radius = 75/6.28

-Result

Radius = 11.94 in ≈ 12 in

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
