Answer:
Step-by-step explanation:
we know that
The equation of the circle in center radius form is equal to
where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have
substitute
Answer:
A =222 in^2
Step-by-step explanation:
A trapezoid has an area given by
A =1/2 (b1+b2) h where b1 and b2 are the lengths of the bases and h is the height
A = 1/2( 21+16) *12
A = 1/2 (37) 12
A =222 in^2

Explanation:
We have:
(

x
+
6
)
Now let's distribute this piece by piece:
(
2
x
)
(
4
x

)
=
8

=
−
