Circle a has center of (6, 7), and a radius of 4 and circle b has a center of (2, 4), and a radius of 16. what steps will show that circle a is
similar to circle b?
translate circle a using the rule (x + 4, y + 3).

Dilate circle A by a scale factor of 4

Step-by-step explanation:

We are given that a circle A with center (6,7) and radius of 4.

Circle B with center (2,4) and radius of 16.

We have to find the steps that will help to show that circle A is similar to circle B.

We know that

All circle are similar in shape.

When two circles are similar then the ratio of radius  is equal to scale factor .

Circle A is dilated  about its center and form  circle B .

Dilation is  that type of transformation in which shape remains same but size of figures change.

Scale factor=

Scale factor=

Hence, the circle A is dilated about its center by a scale factor of 4.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
