Formula of the area of triangle
A=(1/2)a*b*sin(C)
a, b - sides
C- an angle between sides a and b.
Probably, this question means that you need to know sin of the angle.
Answer:
A = 64π units = about 201.06 units
Step-by-step explanation:
The formula for area is
A = πr^2, where r=radius.
Plug in our radius to get the area!
A = π8^2
<u>A = 64π = about 201.06 units</u>
Answer: D
Step-by-step explanation:
Using the equation plot in the coordinates of the points to see if they fit the equation.
5x-3y < 30
A) 5(-3) -3(5) < 30
-15 -15 < 30
-30 < 30 This is true
B) 5(0) -3(0) < 30
0 - 0 < 30
0< 30 This is true
C) 5(-5) - 3(3) < 30
-25 - 9 < 30
-34 < 30 This is also true
D) 5(3) - 3(-5) < 30
15 + 15 < 30
30 < 30 This is not true because 30 is not greater that 30
There are three basic methods for solving quadratic equations: factoring, using the quadratic formula, and completing the square.
