area = pi x r^2
circumference = 2x pi x r or pi x d
1st one diameter = 9.5 cm
so radius = 9.5/2 = 4.75
area = 3.14 x 4.75^2 = 70.85 square cm
circumference = 3.14 x 9.5 = 29.83 cm
2nd one radius = 4
area = 3.14 x 4^2 = 50.25 square cm
circumference = 2 x 3.14 x 4 = 25.12 cm
The answer is 120. Just do 12·12=144. Then 144·5/6=120
Answer:
Arionna is incorrect. There are only 3 cubic feet in a cubic yard because there are 3 feet in a yard, and the proportion will remain constant.

lanation:
The y intercept is at (0, 2) so that means in year 0 it was worth $2.
Its choice C.
Mean = 450 sec
standard deviation = 50 sec
450-50 =400
450+50=500
Between 400 sec and 500 sec means one deviation above and one deviation below the mean, and it is 68%.
68%=0.68
0.68*288= 195.84≈196
Answer is d) 196
