The radius of Circle is 6 cm. The radius of Circle B is 3 cm greater than the radius of Circle A. The radius of circle C is 2cm greater than the radius of circle b. The radius of circle D is 1 cm less than the radius of circle C. What is the area of each circle?How many times greater than the area of circle a is the area of circle D

the area of each circle is =22/7×the number of the area circle

the area of each circle is =22/7×the number of the area circle

Step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
