We know that

[scale factor]=[length miniature skateboard]/[length <span>actual skateboard]
</span>[length miniature skateboard]=3.8 in
[length actual skateboard]=31.75 in
[scale factor]=[3.8]/[31.75]=0.12 in/in

<span>(a) What is the scale factor for the tech deck?
the answer Part A) is 0.12 in/in

</span><span>(b) If the width of the actual skateboard is 8”, what is the width of the tech deck?
</span>[scale factor]=[width miniature skateboard]/[width actual skateboard]
[width miniature skateboard]=[width actual skateboard]*[scale factor]
for width=8 in
[width miniature skateboard]=[8]*[0.12]----------> 0.96 in

the answer part B) is 0.96 in

<span>c) Measure the length of your own foot. If you were designing a doll that was a scale model of you, and you wanted it to be able to use the tech deck as its skateboard, how long should the doll’s foot be?
</span>
the length of my own foot is 25 cm--------> 25/2.54---------> 9.84 in
[scale factor]=[doll foot]/[actual foot]
[doll foot]=[scale factor]*[actual foot]--------> 0.12*9.84-----> 1.18 in

the answer part C) is 1.18 in

a cylinder has a base radius of 2 inches and a height of 9 inches what is the volume in cubic in to the nearest tenth place.
GuDViN [60]

Answer:

113.1 cubic inches

Step-by-step explanation:

The volume of a cylinder is given by the formula:

V=\pi r^2 h

Where

V is the volume

r is the radius

h is the height

Given, h = 9 and r = 2, we substitute and find the volume:

V=\pi r^2 h\\V=\pi (2)^2 (9)\\V=36\pi\\V=113.097

We need answer to nearest tenth, that is 1 decimal place, so we round of the answer as:

113.1 cubic inches
