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.

I really need some help on this question
Leya [2.2K]

Answer:

What is the car's rate in kilometers per minute?

0.9\frac{km}{min}

How many kilometers will the car travel in 5 minutes?

4.5\ km

Step-by-step explanation:

If we know:

\frac{54\ km}{1\ hour}

And there are 60 minutes in an hour:

\frac{1\ hour}{60\ minutes}

We can do:

\frac{54\ km}{1\ hour} * \frac{1\ hour}{60\ minutes} = \frac{54\ km}{60\ minutes} = 0.9 \frac{km}{min}

From here, we figure out the distance from minutes:

0.9\frac{km}{min} * 5 = 4.5\ km
