The response is that the data is not precise
Another way of saying this is "12 is 30% of what number." Knowing that "of" is code word for "multiply" and 30%= 0.30, we can set up this equation, where
x = the unknown number:
To solve for x, all we have to do is divide both sides by 0.30, like so!
The answer is
x = 40, or 30 percent of
40 is 12.
Hope this helps!
Answer:
S = 2 pi (3) squared + 2 pi (3) (14)
Step-by-step explanation:
The formula for the area of a circle is ...
A = πr²
The cylinder has two circular bases with radius 3 cm, so their combined area in square centimeters is ...
A = 2π(3²) . . . . . . matches a term in the last choice
__
The lateral area of the cylinder is the product of the height and the circumference of the base. That is ...
A = 2πrh
For the given radius and height, the lateral area in square centimeters is ...
A = 2π(3)(14) . . . . . . matches a term in the last choice
__
The total surface area is the sum of the areas of the bases and the lateral area, so is ...
S = 2π(3²) +2π(3)(14) . . . . . matches the last choice
_____
<em>Comment on answer choices</em>
We could choose the correct answer based solely on the area of the bases of the cylinder.
X = 4/5 - 3/7
X = 28/35 - 15/35
X = 13/35
