Answer 2

Answer:

Step-by-step explanation:

1.  (8)^2

   = 64 inch(e)

2. area of circle = 2$\pi$r

                          =  2 x 3.14 x 7

                           = 43.96 ≈ 44 inch(a)

3. area of circle = 2$\pi$r

                           =2 x 3.14 x 12

                            = 75.36 ≈ 78 cm^2(a)

4. area of circle = 2$\pi$r

                         =  2 x 3.14 x 1

                          =    6.28 ≈ 12 cm^2(c)

5. area of circle = 2$\pi$r

                          = 2 x 3.14 x 22

                           = 138.16 ≈ 138 in^2(d)
