V=4/3*pi*r^3
dV/dr=4/3*pi*d(r^3)/dr =4/3*pi*(3*r^2)=4*pi*r^2
X+20/2
X/2+10 is the answer
Answer:
D.
Step-by-step explanation:
x = ±√36
x = ±6
hopes this helps :)
Okay so you have to do 5 times 10 then you will have to do 8 time 8 times 40 so after you get your answer you would do the ratio 50 to 320
50:320
