The areas of two circles are in the ratio 49: 64. find the ratio of their circumferences.

7 : 8

Step-by-step explanation:

Given 2 similar figures with circumference ratio a : b

Then the ratio of the corresponding areas = a² : b²

Here the ratio of areas = 49 : 64

Taking the square root of both gives ratio of circumference

ratio of circumference = : = 7 : 8

dont know

step-by-step explanation:

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
