The volume of a sphere depends on its radius, so the volume is a function of the radius. If this function is called VC), use the formula below to compute
(3), the volume of a sphere with a radius of 3 units.

Choice C.:

Step-by-step explanation:

The radius is given as 3, and in the formula you have to cube the radius, meaning you have to multiply 3 b y itself 3 times which gives you 27.  If I were to go further in simplifying the formula, I could come down to , but that answer isn't given as a choice, so I go to the second best answer to get which is answer choice C: .

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
