Answer:
314.16
Step-by-step explanation:
Area=πr2
d=2r
Solving for Area
A=1
4πd2=1
4·π·202≈314.15927
7>6
8>6
9>6
etc.
Possible values for x:
x=7
x=8
x=9
a. 254.34, b. 56.52
a. A = πr^2,
A = 3.14(9^2)
A = 3.14*81
A = 254.34
b. C = πd
C = 18*3.14
C = 56.52
yes is is
if you connect the lines it forms a straight line
