Answer:
73.4 cm^2
Step-by-step explanation:
The equation is :
πr^2
Substitute the radius in:
π(5)^2
Solve:
Area of full circle = 25π
(Note : leave this answer in terms of 'pi' so it is easier to handle
Next, find the area of the sector
The equation for this is:
(angle/360) x πr^2
Substitute the values in:
(80/360) x π(5)^2
Solve :
Area of sector = (50/9)π
Now, find the area of the triangle:
1/2 absinC
Substitute the values in:
1/2(5)(5) x sin(80) = 12.31009691
Subtract this answer from the area of the sector
Answer = 5.14319607
Subtract this from the area of the whole circle
Answer = 73.39662073
To the nearest tenth, that would be 73.4 cm^2
Mark brainliest pls
The photo show how to solve the equation. Also you can use calculator to solve the problem. The easiest way of doing this is using a scientific calculator then use shift solve method for the ans
Add 2 to the interval.
.. [-8, 7]
Consider the range of absolute values of numbers in this interval.
.. [0, 8]
Multiply by -5.
.. [-40, 0]
Add -7.

Answer:
The answer is B because its the same btw i had the same question and got a 100 on the test :)
Step-by-step explanation:
Answer:
0.726 < p < 0.874
Step-by-step explanation:
p = 64/83 = about 0.8
confidence interval = p +- z 
= 0.8 +- (1.64 x 0.04472)
= 0.8 +- 0.073343
= (0.726656 and 0.873343)
0.726 < p < 0.874
