Answer:

Radius = half the diameter.

We have been given the diameter, and need to find the radius.  

Therefore, divide the given values by 2.

1.  12.6 ÷ 2 = 6.3 cm

2.  31.08 ÷ 2 = 15.54 ft

[tex]\sf 3. \quad 10 \frac{7}{11} \div 2=\dfrac{10\times 11+7}{11}\div 2=\dfrac{117}{11}\div 2=\dfrac{117}{11} \times \dfrac{1}{2}=\dfrac{117}{22}=5 \frac{7}{22}\:cm[/tex]

[tex]\sf 4. \quad \dfrac{\sqrt{54}}{2}=\dfrac{\sqrt{9 \cdot 6}}{2}=\dfrac{\sqrt{9}\sqrt{6}}{2}=\dfrac{3\sqrt{6}}{2}\:m[/tex]

5.  10.125 ÷ 2 = 5.0625 in
