qwelly [4]

Answer: 708017151.707 m^3

Step-by-step explanation:

Volume of a sphere has the equation of

V=4/3(pi)r*r*r=4/3(pi)r^3

r=553 m

4/3(pi)553*553*553=4/3(pi)553^3=4/3(pi)169112377

=676449508/3(pi)=225483169.333(pi)=708017151.707 m^3

Where pi=3.14

Hey:) can you please help me posted picture of question
Elina [12.6K]
Answer:
10x⁴ - 33x² - 7

Explanation:
Before we begin, remember the following:
xᵃ * xᵇ = xᵃ⁺ᵇ

Now, for the given:
To solve the given question, we will multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final expression.

This can be done as follows:
(5x² + 1)(2x² - 7)
5x²(2x²) + 5x²(-7) + 1(2x²) + 1(-7)
10x⁴ - 35x² + 2x² - 7
10x⁴ - 33x² - 7

Hope this helps :)

The answer is true.


This is because if you simplify the equation at the left you should get

<em>x-5 = x-5</em>


(x - 5) ^ 3 is equal to (x-5) (x-5) (x-5)

Since it's a cube root you are looking for the same exact number, but in a group 3, there are 3 <em>x - 5 </em>that can form a group and go outside

major arc BRA is 3/2 the length of minor arc BSA. the length of major arc BRA is 6pi centimeters. what is the radius of the circ
tekilochka [14]

9514 1404 393

Answer:

  5 cm

Step-by-step explanation:

The given arcs have the ratio ...

  BRA : BSA = (3/2) : 1 = 3 : 2

Then BRA is 3/(3+2) = 0.6 of the total circumference of the circle.

  0.6(2πr) = 6π . . . . . BRA is 6π long

  r = 6π/(1.2π) . . . . . . divide by the coefficient of r

  r = 5 . . . . centimeters
