Since we know the Circumference of the inner circle, we can divide by (pi symbol) to get the diameter of the inner circle.

87.92/3.14=28

With knowledge of 28 being the diameter, we can also solve for the radius, which is 14.


The area of the inner circle is (pi)14^2

The inner circle’s are is 615.44 unit^2

The outer circle’s radius is 14+7 or 21

(pi)21^2= 1,384.74

We subtract the inner circle’s area from the outer circle’s area.


1,384.74-615.44= 769.3

769.3 square kilometers

The measure of < A is 45 degree
VashaNatasha [74]

We are given \triangle ABC \cong \triangle EFG

The order of the letter sequence is important. The letters pair up based on how they are arranged. We see that A and E are the first letters of the sequences. So this means that angles A and E are the same measure

angle A = angle E

3x+20 = 5x-80

3x-5x = -80-20

-2x = -100

x = -100/(-2)

x = 50

Use this x value to find the measure of angle A

angle A = 3x+20

angle A = 3(50)+20

angle A = 150+20

angle A = 170 degrees

<h3>Therefore, the statement "the measure of angle A is 45 degrees" is <u>false</u>.</h3>
