Find the volume of a sphere with a diameter of 13 in. round your answer to the nearest cubic inch. use pi=3.14
a. 9,198 in^3
b. 862 in^3
c. 1,150 in^3
d. 287 in^3

C.

Step-by-step explanation:

Diameter = Radius/2

So, the radius would be 6.5 in.

The formula for the volume of a sphere is: V = 4/3 (3.14) r^3.

So, once you "plug in" the radius, you get an equation of V = 4/3 (3.14) r^3.

And, once you solve the equation, you get and answer of 1,150 in.^3, rounded to the nearest cubic inch.

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
