Well first find the area of the semi-circle.
If the area of a cricle is equal to pi*radius^2 , then you can just find that and divide by 2.
So, A = pi*2^2. = 4pi
We know that the radius is 2 because the length of the side of the rectangle is 4, meaning that the diameter of the semi-circle is 4, and so the radius is 2 as it is half of the diameter.
We can easily calculate the area of the rectangle, which is
Length * width = 6*4 = 24.
Next we divide 4pi by 2 in order to get the area of the semi-circle, giving us an area of 2pi
We can just subtract 2pi from 24 and get the area of the shaded region.
Area of the shaded region (answer): 17.7
Answer:
Let's use these two sets given to explain what is the domain.
Each value from the left set is x, and from the right is f(x).
If we plug any x from the left set in the function, we'll get f(x) that corresponds to it and that's exactly what the arrows are showing.
Domain of the function is, basically, a set of all values x can have.
In this case, it's easy to see, those are all members of the left set (-6, 1, 5, 8), but sometimes this set can have lots and lots of members, even infinity.
Answer:
8.24 grams/marble
Step-by-step explanation:
Average mass = (total mass)/(number of marbles)
Here, that would be:
824 g
------------------- = 8.24 grams/marble
100 marbles

Answer:
The solution is 8=r
Step-by-step explanation:
When the question states, "What is the distance from the edge of the dart board to the exact center of the bullseye (to the nearest inch)," it is basically asking to find the radius rounded to the nearest whole number given the circumference quantity.
Thus, we need to substitute the numbers already given into the radius equation.
53.3=2 x 3.14 x r
Now, divide both sides by 3.14.
16.97=2r
Again, use division property of equality and divide both sides of the equation by 2.
8.4=r ... then rounding to the nearest inch... 8=r
All things said, the solution is 8=r
I hope this helped!!
