Determine if the sequence below is arithmetic or geometric and determine the

Sonbull [250]

Answer: Arithmetic and 3

Step-by-step explanation:

12 - 9 = 3 9 - 6 = 3 The common difference is equal and is three and so it is an arithmetic sequence

12/9 = 4/3 9/6 = 3/2 The ratio is not equal so this is not a geometric sequence

Finding area of a sector

katen-ka-za [31]

The smaller sector is 360-255=105 degree
it is 105/360 portion of the whole circle, and the area of the whole circle is πr², r is 14
so the area of the smaller sector is (105/360)*π*14²
run those numbers through your calculator, use 3.14 for π, you get 179.5

if you are looking for area of the larger sector, it would be
(255/360)*π*14²=435.94
