Given:
The scale factor between two circles is 
.
To find:
The ratio of their areas.
Solution:
We know that, all circles are similar.
The ratio of the areas of similar figures is equal to the ratio of squares of their corresponding sides or equal to the square of ratio of their corresponding sides.
The scale factor is the ratio of the corresponding sides.
Ratio of areas of circles = Square of scale factor between two circles
Therefore, the correct option is D.
Answer:
Step-by-step explanation:
3.14(pi) X 6 ^2 =
3.14*6 = 18.84
3.14x6^2 =36
your final answer is : B. : 36
Answer:
π
Step-by-step explanation:
the formula is V = πr2h
pie times radius to the second power times hight
Y = 2 ( X - 3 ) ^ 2 - 4 =-4
First you have to convert the numbers to the same units. Either m to cm or cm to m.
To go from meters to centimeters you multiply the number by 100.
7*100=700cm
Now you have 700cm/250cm. This needs simplified
I divided each number by 50 to get 14 and 5
14cm/5cm or 14cm:5cm
