Answer:
So heres what I think
C=2pie r
C=2*3.14*4
c=25.12
So basically half the circle is the radius and the whole is the circumference. So what you are doing is changing pie to 3.14 (since pie=3.14), since half the circle its radius so all you have to do is 2 times 3.14 times 4 to get 25.12 as your circumference.
Hope this helps!

I am not sure but I can give you an app called photo math and they would answer your question. Hope that helped:))
Answer:
c
Step-by-step explanation:
Given
sinN = 
( multiply both sides by b ) , then
a = bsinN → (a)
And
sinM = 
( multiply both sides by y ), then
a = ysinM → (b)
Thus a is both (a) and (b)
Answer:Since the volume of a cylinder formula involves the radius, you can solve for the radius and double it to find the diameter.
Write the formula. Volume=π⋅radius2⋅height.
Substitute the dimensions of the shape into the formula. Use 3.14 as the value for π. 791.28=3.14⋅r2⋅28.
Solve the equation for the variable.

Answer:
<u>Question 1. What function describes the revenue of the tile factory in terms of the tiles sold?</u>
<u>Question 2. What is the flat-fee for delivery?</u>
Explanation:
The equation y - 3,000 = 0.25(x - 10,000) is a linear function written in point-slope form.
- 0.25 represents the slope of the line and is the unit sales price ($ 0.25 per tile).
- (10000, 3000) is the point that represents the sale of 10,000 tiles with a total revenue of $3,000
To answer the first question, you can clear the dependent variable, y, in terms of the independent variable, x:
- y = (0.25x - 10,000) + 3,000
- y = 0.25x + 2,500 + 3,000
And that is the function that describes the revenue of the tile factory in terms of thenumber of tiles sold.
To answer the second question, the flat-fee delivery, you find the y-intercept of the linear function, i.e. the value of y when x = 0:
Hence the flat-fee delivery is $ 5,500.
