Answer 1

The length and area of a circular sector of radius r and angle a are given by:

`\begin{gathered} S=2\pi r\cdot(a)/(360^(\circ)), \\ A=\pi r^2\cdot(a)/(360^(\circ))\text{.} \end{gathered}`

In this problem we have:

• a = 50°,

,

• r = 30 cm.

Replacing these values in the formulas above, we get:

Answers

• S = length = 26cm,

,

• A = area = 393cm².
