Type your questiona circle has a diameter of 81 pie square units. what is the diameter of the circle?

1 answer:

7 0

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

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

100 = -50 + b

150 = b

Farmer Jack needs 1,800 square feet of garden space to have enough corn for a year. His garden space is currently 10 5?6 feet by

sergey [27]

Answer:

$1,605\ ft^{2}$

Step-by-step explanation:

step 1

Find the area of the garden space

First convert mixed number to an improper fraction

$10\frac{5}{6}\ ft=\frac{10*6+5}{6}=\frac{65}{6}\ ft$

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

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.
