Mary removed the dollar sign from (X.)
We know this because $4.00x$5.00=$20.00 so that’s correct and we know that $12.50x $4.00=$50.00. So, our only error here is that there is no dollar sign in our (X) numbers. So that is Mary’s mistake. We can correct it by simply adding a dollar sign to 20 to make $20.00 and adding another dollar sign to 50 to make $50.00

Hope this helps!

How to find the volume of the cone
gavmur [86]

Answer:

The closest measurement to the volume of hat is 84.82 in.³.

Step-by-step explanation:

Given:

The dimensions of hat are height(h) 9 inches and diameter(d) 6 inches.

Now, to find the volume of cone:

Putting the formula \frac{1}{3}\pi r^{2}h.

Radius(r) is not given, finding the radius:

Radius(r)=half of the diameter(d)

r=\frac{d}{2}

r=\frac{6}{2}

r=3.

Then, \frac{1}{3}\pi r^{2}h

=\frac{1}{3}\times\pi \times3^{2}\times9

=\frac{1}{3}\times3.14\times9\times9 (\pi =3.14)

=\frac{1}{3} \times254.34

=\frac{254.34}{3}

=84.78 in.³

So, the volume is 84.78 in.³ .

Therefore, the closest measurement to the volume of hat is 84.82 in.³.
