Answer 1

U should..... Do this sum using this formula u will get the answer.. 22/7(r)^2 - a^2

Answer 2

Answer:=45.718

Step-by-step explanation:

Area of unshaded region = Area of circle - Area of rhombus

                                          =π × r ×r -  1/2× length of diagonal 1 ×length of

                                            diagonal 2

to find length of diagonals;

join OQ and PR

DIAGONALS ARE  PERPENDICULAR BISECTORS

Let intesection point of diagonals be T

PT = TR  and QT = TO

OQ = 8  as it is radius

so QT = TO = 4

OP =OR = 8 --radius

BY PYTHAGORAS THEOREM

TP = TR =√8×8-4×4=4√3 - PR = 8√3

Area of unshaded region =π ×64 - 1/2 × 8√3×8

                                           = 1,408/7 -1/2×64√3

                                          =201.142 - 55.424

                                         =45.718
