Answer:
636
Step-by-step explanation:
the area of the footpath=
(50m+3m+3m)^2-50^2
8 basketballs * 9 inches = 72 (units) of space taken up
Answer:
A = P * a / 2
A = 81.25
Step-by-step explanation:
We have that there is a corresponding formula for a regular decagon, which depends on the apothem and the perimeter, it is the following:
A = P * a / 2
In this case, the perimeter is the sum of all the sides, that is, 10 sides, therefore:
P = 10 * 3.25
P = 32.5 meters
We replace:
A = 32.5 * 5/2
A = 81.25
Which means that for that regular decagon, the area is 81.25 square meters.
ANSWER
D. 135 m^2
EXPLANATION
The area of a kite is half the product of the diagonals.
The first diagonal is
9m+6m=15m
Note that the vertical diagonal is the axis of symmetry of the kite.
This diagonal bisect the kite
Therefore the second diagonal is
2(9m)=18m
The area of the kite
Rate of change
find a2 and a4
a2=27(1/3)^(2-1)=27 times 1/3=9
a4=27(1/3)^(4-1)=27 times 1/27=1
rate of change=(a4-a2)/(4-2)=(1-9)/(4-2)=-8/2=-4
average rate of change is -4
