Which equation listed below, when solved, shows how to find the circumference of a circle if the diameter is 6 inches? Use 3.14
dangina [55]

Answer:

C = π(6)

C = 6π

C = 18.84

Step-by-step explanation:

The circumference is the distance around the circle. It relates the number of times the diameter will encircle the circumference as 3.14 or π. As a result, the formulas for the circumference of a circle are C = 2πr or C = πd. The information given is the diameter so use C = πd by substituting d = 6.

C = π(6)

C = 6π

C = 18.84

PLEASE HELP PLEASE I WILL GIVE BRAINLIEST
aev [14]

Answer:

Step-by-step explanation:

This is a quadrilateral.

Sum of all angles of a quadrilateral = 360

x + 100 + 60 + 95 = 360

        x  + 255       = 360

                        x = 360 - 255

                        x = 105°
