Answer 1

Answer:

4

Step-by-step explanation:

Answer 2

Answer:

4 cm

Step-by-step explanation:

Volume of cylinder = $\pi$r²h

Radius = $\sqrt{\frac{V}{\pi h} }$

Radius = $\sqrt{\frac{351.9}{\pi 7} }$

Radius = $\sqrt{\frac{351.9}{21.98} }$

Radius ≈ $\sqrt{16}$

Radius ≈ 4

So, the radius is about 4 cm.
