Answer:
China´s percentage population is 19%.
Step-by-step explanation:
1. First we need to know the radius of the world´s population.
If India has the 18% of population, and the radius is 3,2 cm, we need to identify the radius of the 100% of population. So we use the next formula:
(3,2 * 100)/18 and the answer will be the radius of the world´s population, that is 17,777 cm.
2. Now, we know the China´s radius (3,4 cm) and the world´s population radius (17,777 cm).
Based on the previuos information we know that 17,777 is the 100%, and we need to calculate the percentage of 3,4.
(3,4*100)/17,777 = 19,12. Round to the nearest percent the answer is 19%.
