Sum of the terms of the series is
Sn = n/2 ( a1+an )
we have n= 6 , a1= 17, an = 57
so Sn = 6/2 ( 17+57) = 3(74) = 222
Answer:
23
Step-by-step explanation:
To find the area of a circle you need to find the radius. You find the radius by dividing the diameter by 2. So in this case, the radius is 14. Multiply 14 by pi and square your answer for the area.
c^2 = a^2 + b^2
looking for C the hypotenuse
a = 35
b = 12
These are the sides
c^2 = 35^2 + 12^2
c^2 = 1225 + 144
c^2 = 1369
Then take the square root of both sides to get C
C = 37
