Question

Answer me to (a) one part

Answer 1

(i) Perimeter = $\frac{3}{4}$ × $\pi$ × (2×14)

                    = 65.97344573

              = 66 cm

(ii) Area of unshaded region = $\frac{3}{4}$ × $\pi$ ×$14^{2}$

                                                = 461.8141201

                                = 462 $cm^{2}$

(iii) Area of shaded area = (28 × 28) +( $\frac{1}{4}$ × $\pi$ × $14^{2}$)

                                        = 937.93804

                          = 938 $cm^{2}$
