Answer:
28.28(simplified from 28.2743338834)
Step-by-step explanation:
area of sector= (center angle/360)*area of circle
we are already given the area of sector as 3/2pi
so
3/2pi=(60/360)*x
(x is area of circle)
3/2pi=4.71238898038
4.71238898038=1/6x
divide both sides by "1/6"
28.2743338834=x
hope this helps!

Answer:
100
Step-by-step explanation:
To make a perfect square trinomial, you want to divide the use the following equation to find the missing constant:
when the quadratic is in standard form.
In this case, we would divide -20 by 2 and square it
-20/2 = -10
(-10)^2 = 100
The exponent tells you how many places to move.
The value is 21 Because three represents those to variables which both equal to 21.
