Answer:
$3203.50.
Step-by-step explanation:
The perimeter of the yard = 2 * 84 + 2 *65 = 298 so we need 298 feet of fencing.
The cost = 298 * 10.75
= $3203.50.
Answer:
13
Step-by-step explanation:
The given expression is (3-2i)(3-2i)
This is of the form (a-b)(a+b)
This is equivalent to , where a = 3 and b=2i
=
=
But
=
=
=
Hence the value of the expression (3-2i)(3-2i) is 13.
Answer:
120
Step-by-step explanation:
add 4 and 2 then multipy by 2 and add a zero
D I am pretty sure is the answer to the question
Volume=heiht times area of base
base=circle
area of circle=pir^2
volume=hpir^2
diameter=2r
diametr/2=r
diameter=8.5
find radius
r=8.5/2
r=4.25
h=11.5
subsitute
v=11.5 times pi times 4.25^2
v=11.5 times pi times 18.0625
v=pi times 207.71875
round to hundreth
v=207.72pi in^3
volue=207.72pi in^3
if you want to aprox pi to 3.14 and solve for that then
v=207.72 times 3.14
v=652.24
so
v=207.72pi in^3 or
v=652.24 in^3 aprox (both aer eequatal)
