Answer:
the solution (x,y) are any x and y that satisfy the equation.
One possible solution is (0,3) or x=0, y=3.
Btw, x(squared) + y(squared) =3(squared)
is an equation of a circle centre (0,0) radius 3.
Where is the question though
Answer:
use formula
area =1/4*π*d^2
81π=1/4*π*d^2(here two pie gets cancel)
81=1/4*d^2
81*4=d^2
=d
18=d
Step-by-step explanation:
For this you would do 4000 x 0.2 which equals 800.
800 acres were not plowed.
Thanks :)
Answer: 88 square inches
If we want to wrap the box, we need to work out its surface area - the area that will need to be covered by the giftwrap.
This box is a cuboid, so there will be six faces, with only three different areas (each face has an identical pair).
Let's say the height is 2 in, the length is 6 in and the depth 4 in.
height = 2
length = 6
depth = 4
Let's find the area of the faces that measure height x length:
2 x 6 = 12 square in
Now let's do the same thing for height x depth:
2 x 4 = 8 square in
And finally for length x depth:
6 x 4 = 24
There are two of each of these faces, so let's multiply each result by two.
12 x 2 = 24
8 x 2 = 16
24 x 2 = 48
Finally, all that's left to do is add these numbers together to find the total surface area of the cuboid.
24 + 16 + 48 =
88 square inches
