Adiagram has circles which represent the populations of various countries in the world. the circle for india has a radius of 3.2 cm and the circle for china has a radius of 3.4 cm. if 18% of the world’s population is in india, what percentage of the world’s population is in china? round to the nearest percent.

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%.
