Answer:
idk go back to 5th grade you might learn how to add but for ur answer is 8
Step-by-step explanation:
Answer: but 8x-4
Step-by-step explanation:
When two events<span> are said to be </span>independent<span> of each other, what this means is that the </span>probability<span> that one </span>event<span> occurs in no way affects the </span>probability<span> of the other </span>event<span> occurring. An example of two </span>independent events<span> is as follows; say you rolled a die and flipped a coin</span>
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
