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.
So,
The range will simply be the absolute value of the difference between the highest and lowest price.
The highest price is $2285.
The lowest price is $1116.
The absolute value of the difference between these two prices is:
|2285 - 1116| = 1169
The range of the prices for the gold phone is $1169.
Answer: i think 300
Step-by-step explanation: i divided 240 by 4 and got 60 then multiplied 60X5=300
