Answer:

The answer to your question is ratio = 9

Step-by-step explanation:

Data

Circle 1 radius = 5''

Circle 2 radius = 15''

Process

1.- Calculate the area of circle 1

Area = πr²

Area = π(5)²

Area = 25π

2.- Calculate the area of circle 2

Area = πr²

Area = π(15)²

Area = 225π

3.- Calculate the ratio of the areas

ratio = 225π / 25π

= 9

masha68 [24]

First we should get the slope.

m=y2 -y1/x2-x1

=2-1/2-0
=1/2

y=m(x-x1) +y1
=1/2(x-0) +1
=1/2x+1
