Answer:

B

Step-by-step explanation:

The equation for the area of a circle is  (pi)r^2

(pi)r^2 = 153.86

3.14(r^2) = 153.86

r^2 = 49

then sqaure root 49

r = 7

r= radius

the diameter would be 7x2 which equals 14

1. How do you use the distance formula and slope formula to classify a quadrilaterals and triangles
4vir4ik [10]

Answer:

Both Distance formula and Slope formula are used to classify quadrilaterals and triangles, as Distance formula is used to calculate the length of each side while Slope formula is used to find the angle of a line with respect to an axis or another line.

We can classify the figure as finding the lengths of each side by using Distance formula. For example, if we find that a quadrilateral has all 4 sides equal, is it a square. If it has opposite sides equal, it can be a rectangle or a parallelogram, and so on. It can also tell whether a triangle is right angled, isosceles or equilateral.

Slope are used to find angles of the lines. If 2 lines have the same slope, it means they are parallel to each other. If the product of their slopes is -1, it means they are perpendicular to each other

<span>let x be the number, then
9x + 15 < or = 10x + 25
then this inequality can be solved
subtract 9x from both sides of < or =
</span><span /><span>15 < or = x + 25
subtract 25 from both sides of < or =
-10 < or = x
this can be written as
x > or = -10 </span>
