Find the areas of the shaded regions.

diamong [38]

Answer:

41.8887 cm^2

Step-by-step explanation:

area of a circle
A = pi * r^2
A = pi * (3 + 4)^2
A = pi * 49
A = 153.94

120 / 360 = 1/3
153.94 / 3 = 51.3134

now area of inner circle
A = pi * 3^2
A = pi * 9
A = 28.274
28.274 / 3 = 9.4247

subtract
51.3134 - 9.4247 = 41.8887

Kitty [74]

Answer:

$\frac{1}{4} x = 4$

Step-by-step explanation:

$\frac{1}{4} x = 4$

Let's solve:

$\frac{1}{4} x = 4$

4( $\frac{1}{4} x = 4$ )

x = 16

Let's check:

$\frac{1}{4} x = 4$

$\frac{1}{4}(16) = 4$

4 = 4

Hope this helps!

Deniz had a full gallon of milk. She poured out 4 cups of milk. There are 16 cups in 1 gallon. About what percent of the origina

Molodets [167]

Answer:

75% of the original volume is left.

Step-by-step explanation:

Deniz had a full gallon of milk, or 16 cups of milk, and then she poured out 4 cups of milk. That is:

$\\ A_{full-gallon} = \frac{16}{16}$ cups of milk, since $\\ \frac{16}{16} = 1$ or $\\ 1 * 100\% = 100\%$ of the original volume.
Deniz poured out 4 cups of milk from the 16 available (or $\\ \frac{4}{16}$ ).

Then,

The total left is:

$\\ Total_{left} = \frac{16}{16} - \frac{4}{16} = \frac{12}{16} = \frac{3}{4}$ , since we are dealing here with fractions with the same denominator.

In other words, $\\ \frac{3}{4} = 0.75$ is the amount of milk left in the container.

In terms of percentage, $\\ \frac{3}{4} = 0.75$ is equivalent to $\\ 0.75*100\% = 75\%$ of the original volume, because Deniz poured out $\\ \frac{4}{16} = \frac{1}{4} = 0.25$ or $\\ 0.25*100\% = 25\%$ from the original volume.
