Hi,
The formula for area of a circle is pi r ^2 so the diameter is 12, therefore the radius is half of that so 6. The answer is 113 km².
Please mark brainliest if I helped!
Answer:
Domain [-5,∞)
Range [0,∞)
Step-by-step explanation:
Part 1) Find the domain
we have

we know that
The radicand must be greater than or equal to zero
so

solve for x
subtract 5 both sides

The solution for x is the interval [-5,∞)
All real numbers greater than or equal to -5
Remember that
The domain of a function is the set of all possible values of x
therefore
The domain of the function f(x) is the interval [-5,∞)
Part 2) Find the range
we have

Find the value of f(x) for the minimum value of x
For x=-5


The minimum value of f(x) is equal to zero
so
The solution for f(x) is the interval [0,∞)
All real numbers greater than or equal to 0
Remember that
The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.
therefore
The range of the function is the interval [0,∞)
To find the surface area of the entire sculpture, you need to add up the surface area of each part of the sculpture. Overall, you see two triangles connected by two rectangles at the top, and the half of a cylinder at the bottom.
To find the area of one of the two triangles, you use the equation A = (1/2)bh, where b = the base of the triangle and h = the height. So, the area of one triangle is:

Hello!
This is a problem about relating values of the Unit Circle.
First, we need to figure out the specific "points" of each angle measure of 30 and 60.
For the angle measure 30, the point will be
.
For the angle measure 60, the point will be
.
The tangent value of a point will be its
value over its
value.

The cotangent value of a point will be the reciprocal of the tangent value, which we found previously.

The sine value of a point will be the
value of the point.

So the values we have so far are 
Now we have to find the LCD to add these together, which in this case would be 6.

Which adds up to
, which is in simplest radical form.
Hope this helps!
