Answer:

around 22, or 21.98

Step-by-step explanation:

s1 =  {r}^{2}  \times \pi = 9 \times 3.14 = 28.26

s2 = 1 \times 3.14 = 3.14

s3 = 28.26 - (3.14 \times 2) = 28.26 - 6.28 = 21.98

kiruha [24]

Answer:

option B

3

Step-by-step explanation:

Given in the question an expression

\sqrt\frac{48}{x}

Whole numbers are positive numbers, including zero, without any decimal or fractional parts.

Possible range of domain will be 1 ≤ x ≤ 48

We know that perfect square between 1 and 48 are

1 , 4 , 16 , 25 , 36

1)

x = 3

√48/3 = √16 = 4

2)

x = 12

√48/12 = √4 = 2

3)

x = 48

√48/48 = √1 = 1
