Which expression gives the volume of a sphere with radius 15?

C) Volume of sphere =  .

Step-by-step explanation:

Given  : sphere with radius 15.

To find : Which expression gives the volume.

Solution : We have given that radius of sphere = 15 units.

Volume of sphere =  .

Plugging the value of radius

Volume of sphere =  .

Therefore, C) Volume of sphere =  .

it would rotate about 180 degrees.

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
