Answer:
3927 square cm
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
