Answer:
115
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 7 - 1 = 13 - 7 = 19 - 13 = 25 - 19 = 6
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 1 and d = 6 , thus
a₂₀ = 1 + (19 × 6) = 1 + 114 = 115

Answer:
Area ≈ 314.16 square inches
Step-by-step explanation:
Radius of circle (r) = ½(20) = 10 in.
Formula for area of circle, A = πr²
Plug in the value into the formula
Area = π × 10²
Area = π × 100
Area = 314.159265
Area = 314.16 in.² (nearest hundredth)
