All your doing is substituting x for the number in the parenthesis and matching it with the correct function. For example, f(-3) would be 2(-3)-7 which is equal to -6-7 which is -13.
Answer:
Our radius is already given, 8.
8 x 3.14 x 2 = 50.24cm <-------- perimeter/circumference
8^2 x 3.14
64 x 3.14 = 200.96cm2 <------- area
Formula of a circumference:
2πr
2 x pie x radius (pie can be used as 22/7 or 3/4 most likely 3.14)
Formula of an area of a Circle:
πr^2
pie x radius squared (pie can be used as 22/7 or 3.14)
