Question

Marble slab creamery is creating a cone-shaped paper wrapper for its new green baby yoda waffle cone. The wrapper should have a radius of 5 cm and a slant height of 10 cm. One location wants to offer the cones a weekend earlier, so they plan to make the cone-shaped wrappers for first 25 waffle cones sold that saturday. About how many square cm of wrapper paper will they nee? (Round to the nearest tenth) Idon't now how to solve the problem

Answer 1

`3927\:cm^2`

Explanation:

Radius of the proposed wrapper= 5 cm

Slant Height of the proposed wrapper= 10 cm

To find out how many square cm of wrapper paper will they need, we need to calculate the combined curved surface area of the wrapper.

Curved Surface Area of a Cone
`=\pi rl`

Total Surface Area of one cone shaped wrapper

`=10*5\pi\\=50\pi \:cm^2`

Therefore:

Curve Surface Area of 25 cone shaped wrapper

`=25*50\pi \\=3926.99\approx3927.0\:cm^2`

They will need 3927 square cm of wrapper paper.
