I am redesigning a rectangular prism in geometry where I have to minimize the surface area while maintaining the same volume. I
Inessa05 [86]

Think about a really long, flat 3-dimensional object. This has a certain volume, and a certain (big) surface area because of its length. Now, make the 3-dimensional object fat and maintain the volume. Notice how you have minimized surface area but maintained volume. This is how I would go about solving it.

Which of the following sequences are not geometric? (check all that apply) a. 2,10,50,250,1250 b. 1,4,9,16,25,36 c. -4,-2,-1,-0.
Romashka [77]
A is geometric because each number is multiplied by 5.

B is not geometric because it is an arithmetic sequence. 

C is a geometric sequence because each number is divided by 2.

D is neither geometric not arithmetic because there is no common ratio and there is not a pattern being added or subtracted to each number.

So, your answer should be B and D.

A cylindrical tube 9.5 cm high and 0.85 cm in diameter is used to collect blood samples. How many cubic decimeters (dmଷ ) of blo
Brums [2.3K]

Answer: 0.539 cubic decimeters of blood can be hold by the cylinder.

Step-by-step explanation:

Volume of cylinder= volume of blood it can hold = \pir^2h

Given :

Height of cylinder (h) = 9.5 cm

Diameter of cylinder (d) = 0.85 cm

Thus radius of cylinder (r) = \frac{\text {Diameter of cylinder}}{2}=\frac{0.85cm}{2}=0.425cm

Putting the values we get:

Volume of cylinder= volume of blood it can hold = 3.14\times (0.425cm)^2\times 9.5cm=5.39cm^3=0.539dm^3 [tex]      (1cm=0.1dm)

Thus 0.539 cubic decimeters of blood can be hold by the cylinder.
