The radius of Circle A is three feet less than twice the diameter of Circle B. If the sum of the diameters of both circles is 49 feet, find the area and circumference of Circle A.

Circumference of circle A = 81.38 feet

Area of circle A = 530.66 square feet

Step-by-step explanation:

We are given the following in the question:

Let r be the radius of circle A.

Then, diameter of circle A = 2r

Let s be diameter of circle B.

The radius of Circle A is three feet less than twice the diameter of Circle B.

Thus, we can write the equation:

The sum of the diameters of both circles is 49 feet.

Thus, we can write the equation:

Solving the two equations, we get,

Thus, radius of circle A is 13 feet.

Circumference of circle A =

Area of circle A =

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
