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 need?

    3,925 cm²

    Step-by-step explanation:

    Wrapper area is equal to the surface area

    Curved surface area of one cone:

    (pi * r * s)

    3.14 * 5 * 10

    157

    For 25 cones:

    25 * 157

    3925 cm²

    3927 square cm

    Step-by-step explanation:

    We want to find the area of the lateral part of the cone with radius 5 and slant height 10. The equation needed is: L = πrl, where r is the radius and l is the slant height. Plug the given values in:

    L = πrl

    L = π * 5 * 10 = 50π square cm

    We want 25 of these, so multiply 50π by 25:

    50π * 25 ≈ 3926.99 square cm ≈ 3927 square cm
