The largest possible circle is cut out of a square whose side length is 8 feet. What will be the approximate area, in square fee

Lunna [17]

Answer:

=13.73 ft²

Step-by-step explanation:

The diameter of the largest possible circle that can be cut out of a square is equal to the length of the side of the square.

Therefore the diameter of the circle cut from a square of side 8ft =8ft

r=4ft

Area of the remaining board= Area of square- area of circle

=side²-πr²

=8²-π×4²

=64-16π

=13.73 ft²

Answer:

Option B

Step-by-step explanation:

Given the following question:

In order to find the answer, we need to convert the scientific notation into standard notation and then simplify by subtracting the decimals. Then we convert the standard notation back into scientific notation.

$0.0007 - (4.9\times 10^{-7} )$
$4.9\times10^{-7} =0.00000049$
$0.0007-0.00000049$
$0.0007-0.00000049=0.00069951$
$=0.00069951$
$0.00069951=6.9951 \times10^{-7}$
$=6.9951 \times10^{-7}$

Your answer is "6.9951 × 10^-7" or option B.

Hope this helps.
