Answer:
3.6 repeating or 3 and 2/3
Step-by-step explanation:
I did the work on a calculator.
(x-center)^2+(y-center)^2=r^2
x^2+y^2=r^2
(5)^2+(-12)^2=r^2
25+144=r^2
169=r^2
r=13
Answer:
its A.
Step-by-step explanation:
Answer:
S₃ = 37
Step-by-step explanation:
given a₁ = 16 and r =
, then
a₂ = a₁ ×
= 16 ×
= 12
a₃ = a₂ ×
= 12 ×
= 9
then
S₃ = a₁ + a₂ + a₃ = 16 + 12 + 9 = 37
