Hoped this helped

Answer 2

C

Explanation:

The smaller cone and larger cone are similar with

ratio of heights = 63 : 189 = 1 : 3

diameter of smaller cone is 24, hence radius is 12

radius of larger cone = 3 × 12 = 36

circumference (C) is calculated as

C = 2πr ← r is the radius

C = 2π × 36 = 72π ≈ 226 mm → C
