Question

solve this unshaded portion​

Answer 1

Step-by-step explanation:

If you observe it correctly

You can see shaded part as part of circle with diameter 14m

So it's are will be

We know area of circle = πr^2

area of 1/4 th part of circle = πr^2 × 1/4

So area of shaded region=

3.14 × 196/4

3.14 × 49

153.86 sq cm.

Area of rectangle =

l × b

60×30

1800 sq cm

So area of unshaded region is

1800 - 153.86

1646.46 sq cm

Hope it helps uh!!

Answer 2

Answer:

CB=30=DA

AB=60=DC

area(rectangle)=l×b

                        =30×60

                        =1800m²

area(sector)=∅/360×πr²

                   =90/360×22/7×14×14

                   =154m²

area(unshaded)=1800-154

                     =1646m²
