Answer

The type of cone shown in the figure is a conical frustum. This type of cone is defined by its two parallel circular bases connected by a constricting surface.

Answer

The labels for the cone are as follows:

A: Vertical height
B: Top radius/Small radius
C: Slant height
D: Base radius/Large radius

Answer

To calculate A–1, we use the formula for the vertical height, calculated as follows:

$A–1 = rac{ ext{sqrt}(480^2 + 700^2)}{700}$

After calculations: $A–1 = 1108.18 ext{ mm}$

Answer

For C–3, we apply the formula:

$C–3 = rac{ ext{sqrt}(250^2 + 120^2 + 700^2)}{700}$

The result is: $C–3 = 752.93 ext{ mm}$

Step 5

Answer

To find X1–X2, we calculate as follows:

$X1–X2 = rac{ ext{sqrt}(480^2 + 700^2)}{700}$

After solving: $X1–X2 = 848.76 ext{ mm}$
