Answer:
the surface area of the cone needed for a waffle cone wrapper is 8.25π square units, or approximately 25.93 square units
Explanation:
We can use the formula for the surface area of a cone to find the surface area of the cone needed for a waffle cone wrapper:
Surface area = πr² + πrℓ
where r is the radius of the base of the cone, ℓ is the slant height of the cone, and π is approximately 3.14.
Since the waffle cone has a radius of 1.5 and a slant height of 4, we can plug these values into the formula and simplify:
Surface area = π(1.5)² + π(1.5)(4)
Surface area = 2.25π + 6π
Surface area = 8.25π
Therefore, the surface area of the cone needed for a waffle cone wrapper is 8.25π square units, or approximately 25.93 square units (if using a calculator to approximate π).
