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
Now you just need to substitute r into the formula for the area of a circle:
=
*16
= 16
(Remember that the area is always given in units squared, in this case cm)
≈ 50.3
Answer: 5a-b+4
Steps:
Reorder and gather like terms
5a+(2b-3b)+4
Collect coefficients of liked terms
5a+(2-3)*b+4
Calculate the sum or difference
5a-b+4
FINAL Answer: 5a-b+4
Assuming this is quadrant one it would be 1,9 after moving left 8 and 5,9 after moving 4 right
