Answer:
326.56 in².
Step-by-step explanation:
<u>Mathematics: Define/explain.</u>
<u>SURFACE AREA:</u> The measure of the total area that an object occupies.
The formula for finding the surface area for a cylinder is:
<u>Mathematics: Solve.</u>
According to the image, the cylinder has a height of 9 inches and a base radius of 4 inches.
Now, we can plug the numbers into the formula.
<u>Mathematics: Conclude.</u>
Therefore, the surface area of this cylinder is 356.56 in².
Answer:
Step-by-step explanation:
Divide the equation by 3, subtract 9, take the square root.
3x^2 + 27 = 0
x^2 + 9 = 0 . . . . . divide by 3
x^2 = -9 . . . . . . . . subtract 9
x = ±√(-9) . . . . . . take the square root
x = ±3i . . . . . . . . . use imaginary numbers to express the root
10 ft i think. 5/9 of 180 (which is 12 x 15) is 100 and 10 x 10 is 100
Let and be the respective radii of balloons A and B. If the fixed total volume is V, then
and knowing and at the start, we have V = 6916π/3 cm³. Then when , the radius of the other sphere is .
Differentiating both sides with respect to time t gives a relation between the rates of change of the radii:
We're given the whole time. At the moment , the radius of balloon B is changing at a rate of
- the formula that represents the equation point- slope is the following y-y1 = m(x-x1) where the point is given (-8,-3) and the slope is -1/9
- then you mus substitute the values in the equation y-(-3) = -1/9[(x-(-8)] , resolving it y+3= -1/9 ( x+8) , y+3 = -1/9x+9/8, y = -1/9x +9/8-3, y = -1/9x-15/8
of this form the equation that represent the form point-slope is
- y+3= -1/9 ( x+8)
