A container with a larger surface area always has a greater volume. Explain whether or not this statement is true using several examples to support your argument.

Answers

No, this is not true every time. It depends on the conditions given.

For example-

Suppose we have a Box A with dimensions 10 x 10 x 1 and Box B with dimensions 5 x 5 x 5.

Box B has a surface area = 2(25+25+25) = 150 and a volume of 5*5*5= 125 cubic units

Box A has a larger surface area = 2(100+10+10) = 240 and a smaller volume = 10*10*1 = 100 cubic units

Similarly take an example of sphere.

Lets suppose the radius of the sphere is 2 cm

So, SA is 4πr² = 4*3.14*2*2 = 50.24 cm²

Volume of the sphere is = 4πr³ /3 = 33.50 cm³

Here also the SA is greater.

PLEASE HELP! Do the angles stay the same degrees when the shape is reduced or enlarged?ex. a triangle is enlarged. do the angles stay the same in the origanal one, and the new enlarged one?

Answers

Well....if the triangle shape stays the same then the angle stays the same even if its enlarged in size. It will stay the same because you didn't change the way the shpae looks like, it is just zoomed in.

Answer: The angle measurements stay the same when the figure is enlarged or reduced

Describe a way that someone could estimate the length of a book

Answers

Answer with explanation:

→The best estimation of a book will be in terms of CM(Centimeter) or Feet.

→We Should use "Centimeter Scale or Measuring tape" for this purpose.

→Otherwise, take a thread ,Put one end of thread on one end of book, that is along the longer side, and keep elongating the thread until you reach the other end.Now, with the help of Different kind of Measuring tape,you can find the length of that thread Accurately.And that will be the length of the book.

Somebody can estimate the length of a book by using a ruler and rounding it to the nearest whole number.

A manatee population decreases by 15 manatees each year for 3 years. Find the total change in the manatee population.

Answers

$total\ change=3\ years\ * 15\ manatee\n\ntotal\ change=45\n\nIn \ 3\ years\ time\ manatee\ population\ decreased\ by\ 45 manatees$

so 15 per year for 3 years or 3 times 15 or 45 total loss so the change is 45 difference or -45 in 3 years
