I need help with recursive form please someone explain this problem!!

Step-by-step explanation:

geometric sequence formula is

An=A1*r^(n-1), where r is the constant by which the terms are constantly getting multiplied,

lets find it: by dividing a term by its preceding term

(1/3)/(1/6)=1/3*6=6/3=2

Thus, the recursive formula for this geometric sequence is:

An=A1*2^(n-1)

11 feet 6 inches and 8 feet 6 inches

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
