How to find the area of a circle with the diameter of 30

A = pi x r^2
r = 30/2 = 15
A = pi(15^2)
A = pi(225) or
A = 3.14(225) = 706.5

First, look and compare at the decimal places in brackets ( ) .

A. (0).561 , (8).627 , (5).325 (wrong)

B. 4.(0)57, 4.(1)22, (5).008 (4.0.., 4.1.., 5.00..) least to greatest - (correct)

C. 1.(7)42 , 1.(5)58, 1.(6)71 - (wrong)

D. Greatest to least - (wrong)
