The graph of the equation 2x=y^2 from A(0,0) to B(2,2) is rotated around the x axis. The surface area of the resulting solid is?
Stolb23 [73]
Write the given equation as
x = (1/2)y² or as y = √(2x)

Graph the given curve within the region (0,0) and (2,2) as shown in the figure below.
When the curve is rotated about the x-axis, an element of surface area is
dA = 2πy dx

The surface area of the resulting solid is
A= 2\pi \int_{0}^{2}  \sqrt{2x} dx =  \frac{4 \sqrt{2} \pi}{3} [x^{3/2}]_{0}^{2} = \frac{16 \pi}{3}

If the right end is considered, the extra area is π*(2²) = 4π

Answer:
The surface area of the rotated solid is (16π)/3.
If the right end is considered, it is an extra area of 4π.

On Wednesday 72% of the costumers who bought gas at a gas station made additional purchases. There were 259 costumers made addit
Fiesta28 [93]

Answer:

360 approx

Step-by-step explanation:

Given data

We want to find the total number of customers that bought gas

Let the total number of customers be x

So

72% of x = 259

let us solve for x

72/100*x= 259

0.72*x=259

x= 259/0.72

x= 359.72

Hence the actual number of customers is 360 approx
