PLEASE HELP!! Find the volume of the sphere rounded to the nearest hundredth

Mathematics
1 answer:
Studentka2010 [4]3 years ago
7 0

Answer:

Step-by-step explanation:

The volume for a sphere is

V=\frac{4}{3}\pi r^3. Our radius is 21 inches, so

V=\frac{4}{3}\pi (21)^3 and

V=\frac{4}{3}\pi (9261). Multiplying straight across the top, using the fact that 3.14 is pi:

V=\frac{116318.16}{3} and divide to get that

V = 38772.72 in^3

The solution for the expression (v²)(m⁴)/(v²)(m³) will be m. The correct option is C.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given expression will be solved as below:-

E =  (v²)(m⁴)/(v²)(m³)

Divide v² by the same term v².

E = (m⁴)/(m³)

E = m

Therefore, the solution for the expression (v²)(m⁴)/(v²)(m³) will be m. The correct option is C.

If you help ill give you some of my banana milk...
snow_tiger [21]

Given:

The function is:

f(x)=4x^2-25x-21

To find:

The domain of the given function.

Solution:

Domain is the set of input values.

We have,

f(x)=4x^2-25x-21

It is a quadratic polynomial.

We know that a quadratic polynomial is defined for all real values of x. So, the given function is defined for all real values of x and the domain of the given function is:

Domain = Set of all real number

Domain = (-∞,∞)

Therefore, the correct option is B.

Determine sun or difference <br> -3 1/3 + 2 2/5
Artist 52 [7]

Answer:

-14/15

Step-by-step explanation:

First, you want to turn each mixed number into an improper fraction. So you get -10/3 + 12/5. Then you want to get the same denominator, and the LCD happens to be 15. You get -50/15 + 36/15. Addition is commutative, so you can do something like this: 36/15 - 50/15. You can do 36-50=-14, and then add the denominator to get -14/15.
