HELP ME PLEASE.what happens to the total volume and surface area when you take two identical cylinders and glue then together by attaching two of their bases so they completely overlap.

Answers

Answer 1
Answer:

Well the total volume doubles, and so does the surface area but you need to subtract 2 bases since they are overlapping each other.


Hope its correct. Good luck! XD

I dont know whats the answer can someone help me ?

Answers

Answer:

V =384 pi  units ^3  

or

V =1205.76 units ^3

Step-by-step explanation:

Volume of a cylinder is given by

V = pi r^2 h

where r is the radius and h is the height

V = pi (8)^2 *6

V = pi (64)*6

V =384 pi  units ^3  (exact answer)

or is we used 3.14 for pi

V = (3.14) * 384

V =1205.76 units ^3

Answer: 1206.37

Step-by-step explanation:

Multiply the pie times the radius and height

3.14 * 8^2 * 6

What is 4 3/4 - 2 2/3

Answers

You have to make the fractions an improper fraction. For 4 3/4 first multiply 4x4 which is 16 then 16+3 which is 19/4. For 2 2/3 multiply 3x2 which is 6 then 6+2 which is 8/3. Now make 19/4 and 8/3 denominators same. 19/4 becomes 57/12 by multiplying 19x3 which is 57 and 4x3 which is 12. 8/3 becomes 32/12 by multiplying 8x4 which is 32 and 3x4 which is 12. Then add 57/12+32/12 which is 89/12. Now make 89/12   into a  mixed number.  The  mixed number is 7 5/12.

What is the greatest common factor of 9 and 11

Answers

ANSWER:

The  Greatest common factor (G.C.D) of 9 and 11 is 1

SOLUTION:

Greatest common factor (G.C.D) is the highest number which is factor for both the given numbers.

Here the numbers are 9 and 11.  

We can find the Greatest common factor (G.C.D) of 9 and 11 using prime factorization method.

In prime factorization method, each number is written as the multiple of their prime factors, after that, on comparison we can find the Greatest common factor (G.C.D).

The prime factorization of  9 = 3 * 3 * 1=1 * 3^(2)

The prime factorization of  11 = 11 * 1 = 1 * 11

We can observe that, greatest common factor for both 9 and 11 is 1.  

Hence Greatest common factor (G.C.D) of 9 and 11 is 1

The GCF of 9 and 11 is 1

What is a mathematical function, equation and expression?

  • function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
  • expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
  • equation : A mathematical equation is used to equate two expressions.

Given is to find the ratio of 15 to 35.

The ratio of 15 to 35 in its lowest terms is -

15/35 = (5 x 3)/(5 x 7) = 3/7

15/35 = 3/7

Therefore, the ratio of 15 to 35 in its lowest terms is 3/7.

If the Pr (A)=0.3 what is Pr (A’)

Answers

Answer:

0.7

Step-by-step explanation:

I assume Pr is for Probability and A' is "not A" (complementary probability)

Pr(Anything)=1

Pr(A)=0.3

Pr(A')=1-Pr(A) (anything but A)

Pr(A')=1-0.3

Pr(A')=0.7

Anita has 4,128 ice cream sticks. She can make a model of a house using 86 sticks. She can make a model of a castle using 96 sticks. If she makes nothing but model houses, how many can she make using all of the ice cream sticks?

Answers

Answer:

48

Step-by-step explanation:

Since she is making only model houses and no castles, we can exclude the number 96 from our equation. Since you want to know 86 x __ = 4,128, you need to divide. 4128/86= 48.
