The volume of a sphere is given by the equation
, where r is the radius.
We are given the diameter of the sphere, but recall that the diameter is twice the radius:
. So the radius is half of the diameter:
.
Half of 8 cm is 4 cm.
We substitute this for r in the equation and we use 3.14 for <span>π.</span>
Actually Welcome to the Concept of the Average rate of change.
The average rate of change can be calculated by, finding the change of the two readings and getting a average between them.
here, for x =3 to x =5
1.) in the interval, x =3 to x = 4
the change is ==> 287 - 125 = 162
2.) in the interval, x = 4 to x=5
the change is ==> 549-287 = 262
Now the average ==> 162+262/2 ===> 212
Hence the average rate of change is 212
Convert 1/4 and 3/10 to have a common denominator:
1/4 = 5/20
3/10 = 620
Now you have 2 5/20 + 4 6/20 = 6 11/20
The answer is A.
Answer:
-2y = 4 - x
2y = x - 4
y = 1/2x - 2
1/2 is the slope of both lines.
y = mx + b
Substitute the given point and the common slope
2 = 1/2 x 2 + b
2 = 1 + b
b = 1
y = 1/2x + 1
The equation of the line that passes through the point
(2, 2) and is parallel to the line x - 2y = 4 is y = 1/2x + 1 or 2y = x + 2.
hope this helps u
