Answer 1

Step-by-step explanation:

Answer 2

Answer:

I) R = 3 cm;

II) V = 14.3 cm³.

Step-by-step explanation:

I) C = 94.2 ÷ 5 = 18.84

A cylinder has a base with a circumference of 18.84cm.

$R=\dfrac{C}{2\pi } =\dfrac{18.84}{2 \cdot 3.14} =\dfrac{18.84}{6.28} =3 \: (cm)$

II) $V=\pi R^{2}H=3.14 \cdot 3^{2} \cdot 5 = 141.3 \: (cm^{3})$
