Answer:
19.6 cm³
Step-by-step explanation:
find h for the large cone V = πr²h/3
66 = π3²h/3
h = 22/π
As the cones are similar, the ratio of the radii will equal the ratio of the heights.
3/2 = (22/π) / h'
h' = 22/π(2/3) = 44/3π
V' = π2²(44/3π)(1/3) = 19.55555... ≈ 19.6 cm³
Answer:
-91w + 60
Step-by-step explanation:
to simplify this -10(10w-6-w)-w
we have,
-10(10w-6-w)-w
-100w + 60 + 10w - w
-91w + 60
