Step-by-step explanation:
Given radius, r = 5,
Circumference of Circle, C

79. Is 52 800 centimeters greater than 1 kilometer?
According to the unit of conversion in every 1 kilometer, there is a total of 100 000 centimeters.
Now, the given value of centimeters is equals to 52 800
=> 1 km = 100 000 cm
=> 52 800 cm is less than the value of 100 000 cm which is equivalent to 1 km.
Thus, the given is not correct. 52 800 cm is less than 1 kilometer.

Answer:
Explanation:
H(t) = -2/5t - 5
-2/5t - 5 = 0
-2/5t = 5
t = 5 x -5/2
t = -25/2
Answer:
The volume for the solid of revolution is
and its value is 401.43623.
Step-by-step explanation:
Since the function is rotating over the y-axis and it is a function in terms of x we can use Shell integration which general formula is given by

a) Setting up the integral.
We are given one end point for x which is x = 2, but we are not given the other, so we can set y = 0 on the given equation to get:

Notice that the exponential function is not going to be equal to 0, so we get the other endpoint for the interval as

which give us

Thus we integate from x = 0 to 2, so we will get:

And we can simplify that to

b) Using a calculator to evaluate the integral.
We can use a calculator to write the integral including the interval to get:

And its value rounded to 5 decimal places is
