Answer:
1. 31.4 cm
2. 15.7 cm
Step-by-step explanation:
Circumference = π X Diameter
Diameter for blue circle = 10 cm
Circumference = 31.4159265 = 31.4 cm
Diameter for orange circle = 5 cm
Circumference = 15.7079633 = 15.7 cm
Answer: -15/56

Step-by-step explanation:
your answer would be x=4 i believe
Increase $110,000 by 20% 3 times.
110,000 x 0.2 = 22000
(0.2 is 20% as a decimal, we needed to convert it to multiply it)
So we must add 22000 to 110,000, then take 20% of the new cost, and repeat.
Add them
110,000 + 22000 = 132000
Take 20% of new value
132000 x 0.2 = 26400
Add that
132000 + 26400 = 158400
Take another 20% of that
31680
Add them
158400 + 31680 = 190080
So the value is now $190,080
A much more efficient way to do this would be multiplying 1.2 instead of 0.2, and skipping the adding part, as you already took 100% of it and are adding 20% more.
Hope this helps!
