If the area of the circle below is 18 ft2, what is the area of the shaded sector? A. 9 ft2
B. 6 ft2
C. 4.5 ft2
D. 13.5 ft2

It would be C

Step-by-step explanation:

since the whole area of the circle is 18 and the sector takes up one-fourth of the circle you would just divide 18 by 4 to get 4.5

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
