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

Someone please help!! find the value of y in this triangle
Ksenya-84 [330]

Answer:

30

Step-by-step explanation:

Triangle containing 120° and y° is an isosceles triangle.

Therefore,

y° + 120° + y° = 180°

2y° = 180° - 120°

2y° = 60°

y° = 60°/2

y ° = 30°

y = 30
