The circumference of a circle is approximately 3.14 times the length of its diameter. Which inequality can be used to find all possible diameter lengths, d, if the circumference of a circle is more than 50 cm? 3.14 d less-than 50 3.14 d greater-than 50 50 d greater-than 3.14 50 d less-than 3.14

3.14 d greater-than 50

(i also need help with one of my questions >~<)

Step-by-step explanation:

Since the circumference of a circle is approximately 3.14 times the length of its diameter, mathematically speaking:

C = 3.14d  

That expression must be greater (>) than 50:

3.14 d > 50

So, the correct option is; 3.14 d greater-than 50

(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
