Volume of a spehere=(4/3)πr³
Data:
diameter=3.5 in
π=3.14
1)we calculate the radius:
r=diameter/2=3.5 in / 2=1.75 in
2) we calculate the volume of this sphere:
volume=(4/3)*3.14*(1.75 in)³=22.4379...in³≈22.44 in³.
Answer: 22.44 in³

Answer:
(x+3)²+(y-4)²=36.
Step-by-step explanation:
For this, we need to use the equation of a circle which is:
(x-h)²+(y-k)²= r²
Simply substitute the center values for 'h,k', and the radius for 'r'.
This will give you:
(x+3)²+(y-4)²=36.

Answer:
x2+11x+28     
Step-by-step explanation:
Thus, (x+7)(x+4) multiplies out to x2+4x+7x+28, which can be simplified to        
                                                      x2+11x+28
