I just did this question: Distance around a circle,C=nd,C=nr-in circumference of a circle
Area of a circle:A=nr,Measured in square units,(radius)(1/2 circumference)
Answer:
Cone
Step-by-step explanation:
Options:
a) Cone b) Cube
c) Cylinder d) Triangular prism
From the given options (a) to (d), option (a) is true.
This is so, because.
The volume (V) of a cone is:

This is as a result of dilating the cylinder by 1/3 whose volume is:

In other words:

<em>i.e. the cross-section of the cylinder (V2) being dilated by 1/3 (which is between 0 and 1) gives the cone (V1)</em>
WXY is a acute angle
YXZ is a acute angle as well
The answer is C 102 degrees. It is so because a triangles 3 angles add up to 180 degrees. If you know 2 of your angles, you would add them together and subtract that by 180 to find your last angle.
The coordinates of vertex G are (2,0). I did this.
