Answer:
64 inches
Step-by-step explanation:
12 x 3ft (1yard)=36in
Answer:
The diameter is 24 so the radius is 12 then we do pi*r^2 or pi*12^2
We can use our numbers and get pi*144 so the area of the circle is 144pi.
If they have given you what pi is
EX:( 22/7 or 3.14)
Just use that instead of pi and multiply 144 to that
Answer:
see bottom
Step-by-step explanation:
divide through by 4
x2 - 2x - 3 = 0
x2 - 3x + x - 3 = 0
(x2 - 3x) + (x - 3) = 0
x(x - 3) + 1(x - 3) = 0
(x + 1) (x - 3) = 0
x + 1 = 0 and x - 3 = 0
x = -1 and x = 3
So 45% OF 40 is
45% * 40
0.45 * 40
that is 18
18 is 18% of what number?
18 = 18% * x
18 = 0.18 * x
divide both sides by 0.18
100 = x
45 % of 40, which is 18, and is 18% of 100.
Hope this helps
