Question

The model rocket nose cone shown below slips into one end of a cardboard tube that has an outside diameter of 31.2 inches. Find the lateral surface area of the nose cone, where *h* = 45.5 in. Give the exact answer and an approximation to the nearest square inch.

Step 1

The diameter of the nose cone is 31.2 inches and height is 45.5 inches.

Lateral surface of a cone is *πrl* square units.

Obtain the radius of the cone.

Step 2

Obtain the slant height of the cone.

Step 3

Now substitutes the value of *r* and *l* in the l...
