Answer:
Radius = 3
Since radius is half of diameter diameter is 6 because 3 x 2= 6
Now I multiply that by pi so...
6 x 3.14 = 18.84 So 18.84 is our answer.
You should be able to find the maximum value of c by simply substituting the maximum values for x and y.
So we'll let x = -2 and y = 6.
The equation is is now as follows:
c = 5(-2) + 4(6)
c = -10 + 24
c = 14
Therefore the maximum value for c is 14.
We determine first the real dimension of the circular fountain by using the scale factor given.
(18 cm) x (4 ft / 3 cm) = 24 ft
Then, calculate for the area of the base of the circular fountain by the equation,
A = πD²/4
where A is are and D is diameter. Substituting,
A = π(24 ft)²/4 = 144π ft² ≈ 452.4 ft²
Thus, the area of the base of the circular fountain is approximately 452.4 ft².
16 because when the line is on the x-axis, it is on zero
