Given:
Radius of the circle = 4 meters
Measure of arc = 135 degrees
To find:
The area of the sector bounded by the given arc.
Solution:
Formula for area of a sector is:
Where, r is the radius and is the central angle or measure of intercepted arc.
Putting in the above formula, we get
Therefore, the exact area of the given sector is square meters.
Answer:
Option B is the correct answer
Answer:
The answer is 4 and -5.
Step-by-step explanation:
Working under the assumption that the first term is not 2x, but 2x², you can find the zero values by factoring the expression:
With it factored we can see that x being equal to -5 or 4 will give a zero value
Let's also see it plotted, as the question said to use a graphing calculator:
Answer:
EH = 10
Step-by-step explanation:
Because F is a midpoint, that means that FG and EF are congruent to each other. So, since FG = 2, that means that EF also equals 2. Because FH also includes FG, you can take the 2 from the FG, and then take that 2 away from 8. Now you know that GH = 6. All that is left is to add all 3 of the units together (2+2+6=10).
