Answer:
50.3
Step-by-step explanation:
area of a circle = πr²
where r = radius
given radius = 4yd
so we have A = πr²
==> plug in r = 4 ( because the given radius is 4yd )
A = π(4)²
==> evaluate exponent
A = 16π
==> simplify 16π
A = 50.3 ( rounded to the nearest tenth )

The tens place keeps on going up each time. You can repeat this same thing with the 2,000.

Just keep on doing that till you reach 9,999
220,000
the thousands column is 5 or more therefore you round up
