A. 36 as the numbers are adding by the next odd integer. An example is: 1–>4 is +3, 4–>9 is +5, 9–>16 is +7, and so on. This rule applies to both of our sequences.
b. 38.
Hope this helps :) brainly if possible so others can see.
The radius is 8
Im not sure if this is what your looking for
C does not represents a function
Answer:
Step-by-step explanation:
The sum of 83 and a number would be as an expression, where 
is "said number".
You would use this formula for the problem...
(C=2πr) The circumference equals 2 multiplied by pi and radius.
In this problem it says diameter, but the diameter is just twice the length of the radius, so just multiply the radius by 2. Plugin your number.
C=2π(2) since 2 is half of 4, that's your radius.
Your answer is roughly C= 12.57.
You're welcome.
