Area = pi r 2
r=10.3
a= pi*10.3^2
a=333.3
Answer:
D
Step-by-step explanation:
Options A & B are multiplied by improper fractions. Therefore,
54 × (5/3) > 54 not < 54
28 × (3/2) > 28 not < 28
Option C should be 49 × (3/7) < 49 not > 49
Whole numbers multiplied by fractions should be smaller.
Hence, option D is the right answer.
Note: Try multiplying like this
(54×5)/3 _ 54
(28×3)/2 _ 28
(49×3)/7 _ 49
(140×2)/5 _ 140
