Answer: A= 380.15
Step-by-step explanation:
To find the area of a circle with the radius, square the radius, or multiply it by itself. Then, multiply the squared radius by pi, or 3.14, to get the area. To find the area with the diameter, simply divide the diameter by 2, plug it into the radius formula, and solve as before.
A= 11^2 ( 3.14)
Answer:
The equation of line is:
Step-by-step explanation:
Given points:
and
To find the equation of the line.
Solution:
In order to find the equation of the line we will first find the slope of the line.
The slope of a line passing through points and the slope can be given as:
Plugging in the given points to find the slope of the line.
Equation of line can be written in point slope form as:
where is a point on the line.
Using point (4,8)
Multiplying both sides by 4.
Using distribution:
Subtracting both sides.
Subtracting 308 both sides.
Multiplying each term with -1.
Thus, equation of line is:
Answer:
6.2 percent
Step-by-step explanation:
47.81 - 45 = 2.81
2.81/45
-2x would be the missing term.
Answer:
D
Step-by-step explanation:
3x * 5x = 15x^2
3x * -3 = -9x
4*5x = 20x
4 *-3 = 12
so 15x^2 +(20x -9x) -12 or 15x^2 +11x -12
