Answer:

D

Step-by-step explanation:

The following ratios are equal in any circle

[tex]\frac{arc}{circumference}[/tex] = [tex]\frac{angle atcentre}{360}[/tex]

Substitute in given values and solve for C, the circumference

[tex]\frac{DE}{C}[/tex] = [tex]\frac{60}{360}[/tex] = [tex]\frac{1}{6}[/tex]

Cross- multiplying

C = 6DE = 6 × 52 = 312 cm → D
