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

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
