Answer:
16.73 to nearest hundredth.
Step-by-step explanation:
The geometric mean of x and y is √xy.

= 16.7332
Answer:
100-25pi m
Step-by-step explanation:
Let us subtract the circles area from the square
<em>First, let us find the area of the square:</em>
Base x height =
10m x 10m = 100m
<em>Now, the circle:</em>
pi x radius ^2 =
pi x (10/2)^2 =
pi x 5^2=
25 pi
Therefore, the shaded area is 100-25pi m. You can also simplify it further by plugging in the 3.14... value into pi.

Answer:
x = -5.39
Step-by-step explanation:
x + (−2.4) = −7.79
x = −7.79 + 2.4
x = -5.39
The ordered pair would be (-5,8)
