Answer:

Step-by-step explanation:

$V= ?\\r = 2\\h = 5\\\pi = 3.14\\\\V = \frac{1}{3} \pi*r^{2} *h\\\\V = \frac{1}{3} *3.14*2^{2} *5\\\\V= \frac{1}{3} *12.56*5\\\\V= \frac{1}{3}* 62.8\\\\V = 20.93333333\\\\\\V = 20.93$

In terms of pi

$V= ?\\r = 2\\h = 5\\V = \frac{1}{3} \pi*r^{2} *h\\\\V= \frac{1}{3} *\pi*2^{2} *5\\\\V = \frac{1}{3} \pi*20\\V= 6.67\pi\\$

Answer:

800 cubic inches

Step-by-step explanation:

So all we need to do is:

1) find the volume of 1 cube

2) multiply it by 100, because 100 cubes make up the prism

SO 1)

The volume of cube = side * side * side = 2*2*2 = 8 cubic inches

SO 2)

The volume of prism = 100 * vol(cube) = 100 *8 = 800 cubic inches

katovenus [111]

What is the question? If it is how long is the total hike, then 17+2=19 (that’s half way).

19x2 =38. 38k is the total round trip of the hike.

Square ABCD is dilated by a scale factor of 2 with the center of dilation at the origin to form square ABCD . What are the coord

kobusy [5.1K]

Answer:

B'(16,14)

Step-by-step explanation:

In square ABCD, A(2,7) C(8,1) D(2,1). First, find the coordinates of the vertex B. From the attached diagram you can see that CD=6 units and is parallel to the x-axis, AD=6 units and is parallel to the y-axis. So, B(8,7).

The origin O is the center of dilation, 2 is the scale factor. The rule of the dilation is

(x,y)→(2x,2y)

Thus,

B(8,7)→B'(16,14) (see attached figure).
