Answer:
c
Step-by-step explanation:
If one square takes 16.4 cm of wire, this means that to form 25 identical squares you need 25(16.4) cm of wire = 410 cm
To convert this to m you just need to divide it by 100 because there are 100 cm in one meter = 4.1 m
Therefore your final answer is: You need 4.1 m of wire to form 25 squares, each with a perimeter of 16.4 cm.
The correct question is
<span>A cylinder has a volume of 320 pi in</span>³<span>. and a height of 5". Find the radius of the cylinder</span>
we know that
[volume of a cylinder]=pi*r²*h----> r²=volume/(pi*h)
r=√[volume/(pi*h)]
volume=320*pi in³
h=5 in
so
r=√[320*pi/(pi*5)]--------> r=8 in
the answer is
8 in

Answer:
12
Step-by-step explanation:
f(x) = 2x^2 - 5x
Let x=4
f(4) = 2 (4)^2 -5(4)
Exponents first
= 2*16 -5*4
Multiply
=32 -20
subtract
=12
