The diameter, D, of a sphere is 15 . Calculate the sphere's volume, V . Use the value 3.14 for pi , and round your answer to the nearest tenth.

Step-by-step explanation:

The formula for the volume of a sphere is V = (4/3)πr³, were r is the radius.  

If we are told only that the diameter is 15, we must find the radius before applying the above formula.  The radius is r = 15/2.

The formula for the volume of a sphere is V = (4/3)πr³ yields

V = (4/3)(3.14)(15/2)^3, or

   =  1,766.3 cubic units

i think it is c hope that

option c is correct.

step-by-step explanation:

the rule regarding the sides of triangle is:

(length of longest side)^2 = square of sum of other two sides.

the sides given are:

6, 10 and 8.

applying the rule we will get:

(10)^2 = (6)^2 + (8)^2

100 = 36+64

100 = 100

so, her answer is incorrect.

no, she should have added 6^2 and 8^2 and compared that to 10^2.

so, option c is correct.
