What is the exact volume of a sphere with a diameter of 18 cm? ______ cm3

Mathematics
1 answer:
madam [21]3 years ago
4 0
The formula to find the volume of a sphere is: V= \frac{4}{3}  \pi r^{3}
Since the diameter is 18 cm, so the radius is equal to r=18/2 = 9
Now we replace r by it's value, so we get: 
\frac{4}{3} \pi  9^{3}
\frac{4}{3}  \pi 729
972 \pi
And we get approximately 3053.63  cm^{3}
Hope this Helps :D

Write the equation of the line, in slope-intercept form, that contains the points (-1,-2) and (1,2)
Bad White [126]
Slope intercept is y=mx+b
m=slope
slope if found by
m=(y1-y2)/(x1-x2)
(x,y)
(-1,-2) and
(1,2)
x1=-1
y1=-2
x2=1
y2=2


m=(-1-1)/(-2-2)
m=-2/-4
m=1/2


y=1/2x+b
solve fo by subsituting one x value
(1,2)
x=1
y=2
2=1/2(1)+b
2=1/2+b
subtract 1/2
3/2=b


equation is
y=1/2x+3/2
