1 answer:
spayn [35]2 years ago

Answer:

7

Step-by-step explanation:

Let the width of the mechanical pencil lead be w_m and the width of a human hair be w_h. We are trying to find the number of widths of pieces of hair (let that be n) that make it equal to the width of a mechanical pencil lead, so we write the equation w_m=n*w_h. Hopefully, writing an equation makes this easier to understand!

Now, I want n, so I divide be w_h on both sides, substitute, and get that n = w_m/w_h = (7*10^-4)/(1*10^-4)

The 10^-4’s cancel, so we get n = 7/1 = 7.

I hope this helps! :)

Find the volume of these solid<br><br>20mm<br>3.7mm<br>41mm​
Reil [10]

The volume of the solid is which is a cone is 100.48 km^{3}.

Given a cone of radius 4 km and height being 6 km.

We are told to find the volume of the cone.

Volume is basically the amount of a substance that a container can hold in its capacity.Its value cannot be equal to zero or negative. It is basically amount of filling in a container.

Volume of cone is 1/3 \pi r^{2} h.

Volume =1/3 \pi 4^{2} *6

=1/3 π*16*6

=32π

=32*3.14

=100.48km^{3}

Hence if the radius of the cone is 4 km and height be 6 km then the volume of the cone is 100.48km^{3}.
