Answer 1

I m not sure about the ans.. I hope it helps you

Answer 2

Answer:

6.5 cm

Step-by-step explanation:

Radius : Height = 14 : 5

Define x:

Let x be the constant ratio

Radius : Height = 14x : 5x

Solve x:

The volume is 308 cm³

πr²h = 308

π(14x)²(5x) = 308

π(14x)²(5x) = 308

3080x³ = 308

x³ = 0.1

x = ∛0.1

x = 0.464

Find the radius:

Radius = 14x = 14(0.464) = 6.5 cm

Answer: 6.5 cm
