Answer:
r= -6
Step-by-step explanation:
expand and get
5r+45-2+2r=1
7r+43=1
7r=1-43
7r=-42
r=-6
Answer:
volume of sphere if radius is divided by 2 is 1/8 of volume of sphere with r radius.
Step-by-step explanation:
The formula to find volume of sphere is:
Volume of sphere = 4/3 π r^3
if radius is divided by 2 i.e r/2
Volume of sphere if r/2 = 4/3 π (r/2)^3
= 4/3 π r^3/8
= (4/3 π r^3) / 8
= (Volume of sphere 1)/8
So, volume of sphere if radius is divided by 2 is 1/8 of volume of sphere with r radius.
There is no difrence between stat and cenrsimete
I believe it would be -4/3.
