Answer:
D 97 cm^2
Step-by-step explanation:
The area of the circle is
A = pi * r^2
We need to convert diameter to r
d =2r
d/2 =r
12/2=r
6 =6
The radius is 6
A= pi *6^2
A = 36 *(3.14)
A = 113.04 cm^2
Now the fraction of the circle that is shaded is 301degrees out of 360
(A circle is 360 degrees)
310/360 * area of a circle
310/360 * 113.04
97.34
To graph a linear function you need to determine two points of said function, plot them in the coordinates system and link them by a line.
The most easy point to find is the y-intersect. This is the value of y when x=0
Replace it in the equation:

The y-intersect is (0, -1)
To determine the second point you have to select any value of x of your choise and replace it in the formula to determine the y-coordinate.
For example: x=4

The coordinates for the second point are (4, 11)
Now plot both points in the coordinate system and the line.
Answer:
Step-by-step explanation:
Area = pi r^2
r = 7 cm
pi = 3.14
Area = 3.14 * 7^2
Area = 3.14 * 7*7
Area = 153.86
Area = 153.9 rounded.
Answer:
x = -13/5
Step-by-step explanation:
let x be the number
8x + 6 = 3x - 7
move variables to left and numbers to right
8x - 3x = - 7 -6
5x = -13
x = -13/5
Answer:
f(- 3) = - 5
Step-by-step explanation:
Given the point (- 3, - 5)
where x = - 3 is the input and y = - 5 is the output
The function can be represented by
y = f(x), that is
f(- 3) = - 5
