Answer 1

Answer:

Step-by-step explanation:

As we know that archery target has circle shape

We know that area of a circle = $\pi$$r^{2}$ [Where  $\pi$ = 22/7(approximate value) and r = radius]

Radius = Diameter/2

The area of gold score = $\pi$$r^{2}$

Radius = 21/2

           = 10.5 cm(or 105/10)

Area = 22/7 X 105/10

        = 11 X 15/5

        = 11 X 3

Area = 33 $cm^{2}$[Area of the gold score]

As given in the question diameter of all the other bands are equal so their radius will surely be equal

So their areas are also equal

The area of all bands except Gold =  $\pi$$r^{2}$

Radius = 10.5/2

            = 5.25 cm(or 525/100)

Area = 22/7 X 525/100

        = 11 X 75/50

        = 11 X 3/2

        = 33/2

Area = 16.5 $cm^{2}$[Area of Red, Blue, Black and White score]
