Q 5) 66.0 square cm

Q 6) 58.1  square cm

Step-by-step explanation:

Q 5)  Let the radii of exterior and interior circles be R and r.

Therefore, R = 5 cm, r = 5- 3 = 2 cm

Area of the shaded region = Area of the exterior circle - Area of the interior circle

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
