6

The way it is written, does not lend itself to an answer. I suppose the closest is A.

7

1 cm = 10 m/s

7 cm = x Cross multiply

x = 7 * 10

x = 70 m/s

8

This problem suffers from the same thing that 7 does. The wording doesn't lead to any answer that is correct. The speed is wrong by a factor of 2 and the direction is is oK at 17o North of East. You are not going to get many answers to this that are in agreement with what you have been given.

9

A Vector has direction and magnitude. That's the definition.

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.
