Answer 2

Answer:

Area of large circle = 314$cm^{2}$  

Area of smaller circle = 50.24 $cm^{2}$  

Area of shaded path = 263.76 $cm^{2}$  

Step-by-step explanation:

Given data

Two circles have same center  

radius of the large circle r₁ = 10 cm

radius of the small circle r₂ = 4 cm

Here we need to find area of the large and smaller circles

and the area between large and small circle

Area of the large circle =  $\pi r_{1} ^{2}$  

                                       =  3.14 (10) (10)  

                                       = 314 $cm^{2}$  

Area of the smaller circle = $\pi r_{2} ^{2}$  

                                          = 3.14(4)(4) = 50.24 $cm^{2}$

The area of the shaded  path between large and smaller circle

                = area of large circle - area of smaller circle

                = 314 - 50.24 = 263.76 $cm^{2}$
