Answer:

The diameter of the circle is $D=36\ in$ and the radius is $r=18\ in$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=\pi D$

where

D is the diameter of the circle

we have

$C=113.04\ in$

substitute and solve for D

$113.04=(3.14)D$

$D=113.04/(3.14)$

$D=36\ in$

Find the radius r

$r=36/2=18\ in$ -----> the radius is half the diameter

Answer:

1237 cubic feet

Step-by-step explanation:

First find the radius of the top D/2=r * r * pi

so 15/2=7.5*7.5*3.14=176.625

then multiply that by the height: 176.625*7=1236.375

So the volume of this figure is 1237 cubic feet!

Hope this helps!! :)

In the data set {3, 7, 1, 4, 5, 7} what is the mean absolute deviation

Radda [10]

The answer would be 11 because you add them all up the divide by how many numbers you have witch is 6 and you get 4.5. Then you subtract 4.5 from all the numbers of the set and take the absolute value then add them all up again and that how you would get 11.hope I wasn’t to late!

I just stuck. Someone explain.

If there are parentheses you add the exponent on the outside to the exponents inside that belong to a variable.

For the three you would just cube it regularly, but for the x you would add the 3 to the 2 that is already on the x
