I think your question should read "A circle has an AREA of 81 PI square units...)
Circle Area = PI * radius^2
81 PI = PI * radius ^2
radius^2 = 81 PI / PI
radius^2 = 81
radius = 9
Therefore circle diameter = 9 * 2 = 18

What is the equation of the line that includes points (25, 100) and (15, 120)
julia-pushkina [17]

Answer:

y = -2x + 150

Step-by-step explanation:

y2 - y1 / x2 - x1

120 - 100 / 15 - 25

20 / -10

= -2

y = -2x + b

100 = -2(25) + b

Answer:

1,605\ ft^{2}

A=\frac{65}{6}*18=195\ ft^{2}

step 2

Find how much more land Farmer Jack needs to plant the rest of his corn

1,800\ ft^{2}-195\ ft^{2}=1,605\ ft^{2}

The number of visitors to an annual neighborhood carnival increased each year as shown in the table. Predict the number of visit
valentinak56 [21]
The average rate of change of the population from 2007 to 2012 is

\dfrac{669-524}{2012-2007}=29

which is to say that every five years you can expect 29 more visitors.

So if there were 607 visitors in 2010, then you could expect around 607+2*29=665 visitors in the year 2020.
