A 3 cm x 3 cm rectangle sits inside a circle with radius of 4 cm.
Ivanshal [37]

Step-by-step explanation:

you did not show us the picture or described what the shaded area is.

I assume it is the area of the circle without the inner square (as the "rectangke" is actually a square, because its sides are equally long).

so, we need to calculate the area of the circle and subtract the area of the square.

the area of the square is 3×3 = 9 cm².

the area of the circle is

pi×r²

with r being the radius.

so,

pi×4² = pi×16 = 16pi

the shaded area is then

16pi - 9 = 41.26548246... cm² ≈ 41.27 cm²

nothing of the answer options seems to be in that area, so maybe my assumption about the shaded area is wrong. or the specified answer options are mistyped. or both.

anyway, without additional information that is the best I can do.

How do u do 389.2÷28 in 5 grade standard algorithm show work
Mashutka [201]

Answer:

  see attached

Step-by-step explanation:

Each digit of the quotient is aligned with the least significant digit of the current dividend. The "current dividend" is that portion of the remaining dividend that is at least 1 and less than 10 times the divisor. The product of the quotient digit and the divisor is subtracted from the "current dividend" to get the remaining dividend.

__

For many folks, the hardest part of this algorithm is determining the appropriate quotient digit, and multiplying that by the divisor. Some teachers teach that you start this process by making a list of the multiples of the divisor:

N . . . 28N

1       28

2      56

3      84

4      112

...

This process can be aided by your number sense.

2N is simply N added to itself.

3N is N+2N.

4N is double 2N

5N is half of 10N.

You can proceed to build the table by adding 28 to each previous value, or by recognizing doubles and halves and other sums.
