What is the volume of a sphere with diameter of 4 millimeters
marin [14]
The volume is 33.5mm^3 (or cubed)

Formula : v = 4/3πr^3 or v = 4 x 3.14 x (r x r x r) <span>÷ 3
</span>
~ 2 x 2 x 2 = 8  (we use 2 because the radius is half of the diameter)

v = 4 x 3.14 x 8 <span>÷ 3     a. Multiply everything together
v = 100.48 </span><span>÷ 3             b. Divide by 3</span><span>
v = 33.493                   c. Round (if needed)
</span>v = 33.5

What is the minimum value for y= 3cosx?
VashaNatasha [74]
Take the deritive
y'=-3sinx
find whre it equals 0
it equals 0 at -pi, 0, pi, etc
find whre it changes from negative to positive
at -0.5pi, the derivitive is positive
at 0.5pi, the deritivie is negative
changes from positive to negative at x=0
that means that the max values are at pi and -pi in 2pi intervals

-pi, pi, 3pi, 5pi,etc
the min y value is -3

so the minimum(s) are/is at (2aπ,-3) where 'a' is an integer
