I need help pleasse.

Diameter = 7, Radius = 3.5

Radius = 9, Diameter = 18

Diameter = 12, Radius = 6

Radius = 2.5, Diameter = 5

Step-by-step explanation:

The diameter is the largest line that can be drawn in a circle. It passes from one end of the circle to another, and it goes through the center of the circle. The radius is a line drawn from the center of the circle to the circumference of a circle. By its definition, the radius will always be half of the diameter. Use this information to find the radius of the circle when given the diameter,

Diameter = 7, Radius = 3.5

Radius = 2.5, Diameter = 5

answer: your gay

step-by-step explanation:

you dont know math

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
