A quarter has a diameter of approximately 24 millimeters. What is the approximate area of the quarter ? Answer choices:
75.36 mm square
452.16 mm square
150.72 mm square
1,808.64 mm square

452.16

Step-by-step explanation: The formula for area is A=πr². The radius is half of the diameter, which would give us 12. so just plug in. 12² is 144. 144π is 452.38. (Which is close to 452.16) Hope this helps :)

(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
