100 = (5)²θ

100 = (25)θ

4 = θ

Answer: 1570.80 cm²

Step-by-step explanation:

A = $\frac{1}{2}$r²θ

A = $\frac{1}{2}$(100)²$(\frac{\pi}{10})$

A = 500π

A = 1570.80

Answer: 19.63 m²

Step-by-step explanation:

A = $\frac{1}{2}$r²θ

  = $\frac{1}{2}$(5)²$(\frac{\pi} {2})$

  = $\frac{25\pi} {4}$

  = 19.63

Answer: 15°

Step-by-step explanation:

$\frac{\pi }{180} = \frac{\pi} {12x}$

180 = 12x

  15 = x
