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.

Answer:
6.40 saved 33.60 needed
Step-by-step explanation:
She needs $40 *16% = $6.40
$6.40 saved - $40 = $33.60 needed
Answer:
there were 50 apples at the store. 12 of them were green, how many of the 50 apples were red?
Step-by-step explanation:
Diameter of cone = d = 4mm
So,
Radius of cone = r = 2mm
Slant Height = l = 6mm
Surface Area = A = ?
The formula for the surface area of cone is:
Using the values, we get:
mm²
Therefore, the surface area of the cone with diameter 4mm and slant height of 6mm will be 16π mm²
