PLEASE ANSWER QUICKLY!!The diameter, D, of a sphere is 10.4 mm. Calculate the sphere's volume, V.
Svetlanka [38]

Answer:

About 588.7 mm^3

Step-by-step explanation:

The formula for the volume of a sphere is (4/3)*pi (or in this case 3.14)*r^3, where r is the radius.

We need the radius. We are given the diameter, 10.4.

The radius is half the diameter, so 10.4/2=5.2.

Use r=5.2 and put it into the formula:

(4/3)*3.14*5.2^3≈588.7

By what number should-15/56 be divided to get -5/6<br><br>pls pls pls pls I need your help ​
mr_godi [17]

Answer:

The desired divisor is n = 21

Step-by-step explanation:

Let that number be n.  Then:

-15/56        -5

---------- = ---------

     n            6

Through cross-multiplication we get:

(-15/56)*6 = -5n, which reduces to:

(-15)(7) = -5n, or 3(7) = n

The desired divisor is n = 21

The figure shown is formed by the arcs joining the midpoints of the four sides of a square with a side length of 15 centimeters.
Mademuasel [1]
Ok so if The area of the square is 15 * 15. then what you need to do is subtract the total area of the 4 white sectors of a circle. Together, the 4 sectors form one circle of radius 7.5. Now yu need to have in mind that the area of the circle they jointly form is pi * (7.5)^2. So  15 * 15 - pi * (7.5)^2 =<span>48.29
Hope this is useful</span>
