The sum of the convergent series
is 5.31
For given question,
We have been given a series 
We need to find the sum of given convergent series.
Given series is a geometric series with ratio r = sin(1)
The first term of the given geometric series is 
So, the sum is,
= 
= sin(1) / [1 - sin(1)]
This means, the series converges to sin(1) / [1 - sin(1)]

=
= 
= 
= 5.31
Therefore, the sum of the convergent series
is 5.31

Answer:
Area of shaded region = 329.70 cm²
Step-by-step explanation:
Area of a circle = πr²
Area of bigger circle = 3.14 × 11²
= 3.14 × 11 × 11
= 379.94 cm²
Area of smaller circle = 3.14 * 4²
= 3.14 × 4 × 4
= 50.24 cm²
Area of shaded region
= Area of bigger circle - Area of smaller circle
= (379.94 - 50.24) cm²
= 329.70 cm²
