Answer:

63.59 in²

Step-by-step explanation:

The formula to find the area of a square: a², where a is the side.

The formula to find the area of a circle: πr², where r is the radius (diameter ÷ 2), and the pi is alterable (3.14 or 3.142 or 22/7).

1) Find the diameter of the circle. The side of a square is the diameter.

a²

a = √81

a = 9

2) Plug the values into the formula of the area of a circle. 9 ÷ 2 = 4.5 (radius).

= 3.14 x 4.5²

= 3.14 x 20.25

= 63.585

3) Round off the result to the nearest hundredth.

= 63.59

Vika [28.1K]
This is a linear relationship as the rate of change is constant, ie constant velocity.  And the slope represents the velocity, and slope is:

m=(y2-y1)/(x2-x1)

m=(50-25)/(2-1)=25/1

m=25

So the rate of change is 25 mph

mezya [45]

Answer:

100 - (Probability for raining + Probability for fight delay + Probability for Raining and fligth delay ) = Probability for no rain and flight on time.

So, 100-(0.17+0.16+0.07) = Probability for no rain and flight on time.

100-(0.40) = Probability for no rain and flight on time.

99.60=Probability for no rain and flight on time.
