The terms in the sum are given by the sequence
We have
for all 
, and the series 
clearly diverges, so 
must also diverge.
Answer:
a² + b² = c²
13² + 13² = c²
169 + 169 = c²
338 = c²
c = √338 or 18.385 or 13√2
Perimeter of the arc = 1/2 πD
Perimeter of the arc = 1/2 x π x (16 x 2)
Perimeter of the arc = 50.27mm (Nearest hundredth)
Perimeter of the figure = 50.27 + 20 + 20 = 90.27mm
------------------------------------------------------
Answer: Perimeter = 90.27 mm
------------------------------------------------------
To find the area of a trapezoid it (top length + bottom length)/ 2 times height
Top length is 9
Bottom length is 19
(9+19)/2 x height = area
Area=168
14x height=168
Height =12
