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.
[tex]R=\dfrac{C}{2\pi } =\dfrac{18.84}{2 \cdot 3.14} =\dfrac{18.84}{6.28} =3 \: (cm)[/tex]
II) [tex]V=\pi R^{2}H=3.14 \cdot 3^{2} \cdot 5 = 141.3 \: (cm^{3})[/tex]
