Ascuba diver descended at a rate of 2 1/4 feet per second. if 0 represents the surface of the walter and distance is below the surface are negative, which expression represents one way to calculate the location of the river after 12 1/2 seconds? a) 12 1/2 - 2 1/4 b) 12 1/2 + 2 1/2 c) 12 1/2 x 2 1/2 d 12 1/2 x (-2 1/4)

D if the diver is descending at that rate each second the feet per second would be found by multiplying the seconds by the distance per second

area of a circle
area = pi r ^2 
64 = 3.14 x r ^2
divide both sides by 3.14 
20.38 = r^2 
square root of 20.38 
4.51 = r 
diameter is twice the radius 
4.51 + 4.51 = 9.02
