Answer:

d

Step-by-step explanation:

Soooo,

d = 2r

(29) = 2r

29/2 = 2r/2

14.5 = r

A volleyball uniform costs $15 for the shirt, $12 for shorts, and $8 for socks. Which expression applies the distributive proper

bixtya [17]

Answer:

I think it would be 350$

Step-by-step explanation:

ok so you have to buy 10 shirts so you need to set up your problem which would be 10(12+8+15)

Then you would have to actually distribute which would give you 120+80+150

Finally you just add all of your numbers together which would be 350$

Use the shell method. Each shell has a height of 3 - 3/4 y ², radius y, and thickness ∆y, thus contributing an area of 2π y (3 - 3/4 y ²). The total volume of the solid is going to be the sum of infinitely many such shells with 0 ≤ y ≤ 2, thus given by the integral

$\displaystyle 2\pi \int_0^2 y \left(3-\frac34 y^2\right) \,\mathrm dy = 2\pi \left(\frac32 y^2 - \frac3{16} y^4\right)\bigg|_0^2 = 6\pi$

Or use the disk method. (In the attachment, assume the height is very small.) Each disk has a radius of √(4/3 x), thus contributing an area of π (√(4/3 x))² = 4π/3 x. The total volume of the solid is the sum of infinitely many such disks with 0 ≤ x ≤ 3, or by the integral

$\displaystyle \pi \int_0^3 \left(\sqrt{\frac43x}\right)^2 \,\mathrm dx = \frac{2\pi}3 x^2\bigg|_0^3 = 6\pi$

Using either method, the volume is 6π ≈ 18,85. I do not know why your textbook gives a solution of 90,43. Perhaps I've misunderstood what it is you're supposed to calculate? On the other hand, textbooks are known to have typographical errors from time to time...
