By the segment length postulate, the length of RC equals the length of RW + length of WC.

RC = RW + WC

126 = RW + 72

54 = RW Answer B

Estimate the product of<br> 5<br> and 4<br> Then find the product.

Nana76 [90]

1: Look at the 4, its a lot easier to multiply 5 x 5 rather than 5 x 4, plus if you are estimating, you are going to round either up or down.

2: Multiply 5 x 5 // the answer is 25.

3: Multiply 5 x 4 (the original) // which is 20.

Use the method of cylindrical shells to find the volume generated by rotating the region bounded by the given curves about the s

Furkat [3]

Answer:

$\frac{16\pi}{3}$ .

Step-by-step explanation:

I graphed the region in the image below. The blue line is y=3, the purple line is x=1 and the green curve is y = $4x-x^{2}$ . The shaded region in blue is the region we are going to rotate.

Now, to find the volume v= $2\pi \int\limits^a_b {p(x)h(x)} \, dx$ where a=1, b=3 (left and right points of the region), p(x) is the distance from the rotation axis to the diferential Δx, we say p(x)=x and h(x) is the height of the region, in this case is h(x)= $4x-x^{2}-3$ . Then,
