The first investor you invested $180,000 the second $270,000 and the third $450,000. Solution: 2+3+5=10 900,000/10=90,000 90,000x2=180,000 90,000x3=270,000 90,000x5=450,000
To find the circumference of a circle that lists only as a diameter, you would do pi*d so lets say the diameter is 6, you would do pi*6 which would end up giving you 18.84. I hope this helps a bit! (:
