Answer 1

Answer:

Step-by-step explanation:

Arc length of the circle is given by,

Arc length = $\frac{\theta}{360^{\circ}}(2\pi r)$

Area of the sector of a circle = $\frac{\theta}{360^{\circ}}(2\pi r)$

22). Arc length of the circle having central angle = $\frac{\pi}{3}$

                                                                                 = 60°

Arc length = $\frac{60^{\circ}}{360^{\circ}}(2\pi )(7)$

                 = $\frac{14\pi }{6}$

                 = 7.33 cm

23). Arc length of the circle having central angle = 225°

Arc length = $\frac{225^{\circ}}{360^{\circ}}(2\pi )(10)$

                 = 12.5π

                 = 39.27 km

24). Central angle = $\frac{5\pi }{4}$

                              = $\frac{5\times 180^{\circ}}{4}$

                              = 225°

Area of the sector = $\frac{225^{\circ}}{360^{\circ}}(2\pi )(11)$

                               = 43.20 yd²

25). Area of the sector = $\frac{270^{\circ}}{360^{\circ}}(2\pi )(14)$

                                      = 65.97 yd²
