Use the picture of the circle below to find the area of the circle. Use 3.14 for π and show your work.

254.34 in^2

Step-by-step explanation:

To calculate the Area of Circle is πr^2

r is the radius of the circle

In this problem, the diameter is given which is 18 in. To find the radius you have to divide the diameter by 2.

18/2 = 9 in is our radius

Area of Circle = π9^2

                       = 3.14*81

                       = 254.34 in^2                    

answer: for each 3 girls there is 2 boys . 3: 2

hope this ! (:   mark me as brainliest if you can

see explanation

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
