Answer:
Step-by-step explanation:
r = 3 in
h = 7 in
volume of cone = ⅓πr²h = 21π in³
cylinder has radius r = 3 and height h.
volume of cylinder = πr²h = 9πh in³
volume of cylinder is two times the volume of cone
9πh = 2×21π
9h = 42
h = 42/9 = 4⅔ in
13: 72.25
14: 52
For 14, you need to split the figure into a triangle and rectangle.
Answer:
c≥2(x-2) ÷ 5
Step-by-step explanation:
5c+3≥6x-8
5c ≥6x-8-3
5c≥6x-12
c≥(6x-12) ÷ 5
c≥ 2(x-2) ÷5
The answer is to solve each expression.
