Answer:
4000 sq inches
Step-by-step explanation:
A rectangle is given with sides 82 and 46 inches
We have to round off these dimensions to the nearest 10.
82 inches ~80 inches since 2 <5, we make it 0
Similarly 46 inches ~50 inches since 6>5
Now area
= length x width
=80(50)
=4000 square inches
Option 2 4000 sq inches is correct answer.
Answer:
7.722cm^2, x=129
Step-by-step explanation:
12*12=144- area of the whole square
the diameter for the circle is 12
radius is 6
Area for circle= pi* r²

144-113.112=30.888
30.888/4=7.722
