A group of students stood in a circle to play a game. The circle had a diameter of 15 meters. Which measurement is closest to the circumference of the circle in meters?

47cm

Step-by-step explanation:

Thw circumference of a circle is given as: = 2πr or πd

where

π = 3.142

d = diameter = 15 meters

Circumference = πd = 3.142 × 15

= 47.13 cm

= 47cm

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
