Answer:
The formula for working out the area of a circle is
. r stands for the radius. The radius is the diameter divided by two.
r = d/2
r = 8cm/2
= 4cm

=
*16
= 16
(Remember that the area is always given in units squared, in this case cm)
≈ 50.3
Answer:
8x
Step-by-step explanation:
Because you are adding the (x+3) there you can immediately you the association property to simplify
(2x + 5x + x) + (3 - 3)
8x + 0 =
8x
