Hi there! The answer is ( - 7, 5)
The standard form of the equation of a circle is the following:
In this equation r represents the radius of the circle and the point (a, b) is its centre.
Therefore, the centre of the circle
is the point ( - 7, 5).
Answer:
16/33
Step-by-step explanation:
12C4(total possible outcomes)=495
Since there are 6 married couples there must be 6*[2C2×10C2]=270
must subtracted 15 since when there are 2 couples in a group would have doubled 270-15=255
the no of groupings with no married couples 495-255 =240
probability=no of favourable outcomes /no of possible outcome
probability=240/495= 16/33
<h3>Given</h3>
a cuboid with length, width, height dimensions 5, 6, x
<h3>Find</h3>
the value of x that makes the numerical value of the total surface area equal to the numerical value of the volume
<h3>Solution</h3>
The volume is given by
... V = L·W·H = 5·6·x = 30x
The area is given by
... A = 2(L·W + H(L+W)) = 2(5·6 +x(5+6)) = 2(30 +11x) = 60 +22x
When these are equal, we have
... 30x = 60 +22x
... 8x = 60
... x = 7.5
The desired value of x is 7.5.

Step-by-step explanation:
Answer:
≈ 38.14 cm²
Step-by-step explanation:
Diameter of circle= 6.97 cm
Area of circle = ?
- Area = πr² = πd²/4 =
- 3.14*(6.97)²/4 ≈ 38.14 cm²
