Pi * 5 squared = 25 Pi
25 Pi * 5 = 125 Pi or 392.6990817
and I'm not sure how to round to inch cube sorry. :(
The diagnonals of a parallelogram bisect each other ,
so
=》 BD = 3x × 2
=》BD = 6x
and there's given that
=》

=》

=》

=》

so, if x = 4 , then the given quadrilateral is a parallelogram.
Answer:
115*
Step-by-step explanation:
Because the angles are interior angles they are going to be equal to 180. So 180-65=115
Answer:
x=60
Step-by-step explanation:
basically you know the green part is 30, the part on the right is 90. 90+30=120
180-120=60
Solution:
f(x) = 2x + 3
g(x) = x - 9
f(x) + g(x)
= (2x + 3) + (x - 9)
= 2x + x + 3 - 9
= 3x - 6
