Answer:
1 : 4 : 9
Step-by-step explanation:
Given the ratio of diameters = a : b , then
ratio of areas = a² : b²
Here ratio of diameters = 1 : 2 : 3 , so
ratio of areas = 1² : 2² : 3² = 1 : 4 : 9
Answer:
a. area=452.16 sq m
circumference=75.16m
b. area
c. circumference

Answer:
25
Step-by-step explanation:
125^2=125*125=15625
125^4/3=cube root of 125^4=cube root of 244240625=625
15625/625=25
