The value of f(1) = 81
Step-by-step explanation:
For the recursive function, f(n+1) = one-half(n)
Thus, when n = 2,
f(3) = 9
If n = 1,
f(2) = 9×3
f(2) = 27
If n = 0,
f(1) = 27 ×3
f(1) = 81

Answer:
Yes
Step-by-step explanation:
Theorem 8.3: If two angles are complementary to the same angle, then these two angles are congruent.
Since the circumference is 80, you know that the equation used was:

Divide by pi and you'd get d = 25.465
Divide that by 2 to get your radius.
25.465 / 2 = 12.723 = r
The area formula for a circle is

So,

= 508.544 square feet
