Answer:
25.1325
Step-by-step explanation:
16/2= radius of 8. pi*r^2 for 8 is 201.06. 201.06/8(slices) = 25.1325
Answer:
the third
Step-by-step explanation:
your photo is not clear, and your explanations for your question is not clear also.
as we are tackling the substraction and the addition questions between matricxs.We could simply +/- every number correspondingly.
Answer:

Step-by-step explanation:
The volume of a cylinder is given as:

Since the diameter is
, the radius is
.
Therefore, the volume of this cylinder is:
, using
as requested in the problem.
Since the tank is emptied at a constant rate of
, it will take
to empty the tank.
Answer:
The slope of the new road is 0.
Step-by-step explanation:
- the slope of d street line is tan(90)
[if the angle made by a line with x axis is
then, the slope of that line will be tan(
) ]
- here, the angle made by the d street line with x axis is 90 degrees.
- if a road is to be built which is perpendicular to d street , it should make 0 degrees i.e, it should be parallel to x axis .
- so, the slope of new road will be tan(0) = 0
L = total length
D = number of days
they add 3 miles per day which = 3D
equation: L = 59 +3D
if they worked for 34 days, replace D with 34 to get:
L = 59 +3(34) =
L=59 + 102
L=161 miles total length after 34 days
