length \: of \: 1 \: side = diameter

area \:  =  {l}^{2}  \\ 100 =  {l}^{2}  \\  \sqrt{100}  = l \\ l = 10

diameter = 2 \times radius \\ 10 = 2 \times radius \\ radius = 5

circle \: area = pi \times  {r}^{2}  \\ circle \: area = 3.142 \times  {5}^{2}  \\ circle \: area = 3.142 \times 25 \\ circle \: area = 78.55 {cm}^{2}

Answer:

first blank = 39

second blank = 28

Step-by-step explanation:

11 + __ + 7 + 28 = 85 = 39 + __ + 11+ 7

since,, four terms add upto form 85 out of which two terms (11 and 7) are common. so, the first blank will be filled with 39 and second blank with 28.
