Answer:

C and D

Step-by-step explanation:

1

The arc length is calculated as

arc = circumference of circle × fraction of circle

= 2πr × $\frac{60}{360}$

= 2π × 10 × $\frac{1}{6}$ = $\frac{20\pi }{6}$ = $\frac{10\pi }{3}$ cm → C

-----------------------------------------------------

2

The area (A) of a sector is calculated as

A = area of circle × fraction of circle

= πr² × $\frac{60}{360}$

= π × 10² × $\frac{1}{6}$ = $\frac{100\pi }{6}$ = $\frac{50\pi }{3}$ cm² → D
