Find the area of the shaded portion in each of the following​
MrRa [10]

Answer:

30.5 cm^2

Step-by-step explanation:

<h3><u>General outline</u></h3>
  1. Find the area of the full circle
  2. Find the area of the rectangle
  3. Find the difference (full circle area - rectangle area)

<h3><u>Step 1.  Find the area of the full circle</u></h3>

Recall the formula for the area of a circle: A_{circle}=\pi r^2 where \pi \approx 3.14, and "r" is the radius of the circle (distance from center to any point on the edge).

From the diagram, the radius is 5cm.

A_{circle}=\pi r^2

A_{circle}=(3.14)(5[cm])^2

A_{circle}=78.5[cm^2]

<h3><u>Step 2.  Find the area of the rectangle</u></h3>

Recall the formula for the area of a rectangle: A_{rectangle}=bh where "b" is the base of the rectangle (length of bottom or length of top), "h" is the height of the rectangle (distance from bottom to top).

From the diagram, the base is 8cm, and the height is 6cm.

A_{rectangle}=bh

A_{rectangle}=(8[cm])(6[cm])

A_{rectangle}=48[cm^2]

<u />

<h3><u>Step 3.  Find the difference (full circle area - rectangle area)</u></h3>

Having found the areas for each of the first parts, we can find the difference to find the shaded area:

A_{shaded}=A_{circle}-A_{rectangle}

A_{shaded}=(78.5[cm^2])-(48[cm^2])

A_{shaded}=30.5[cm^2]<u />

PLEASE HELP!! The area of a square is 16 square units. Since 4^2 = 16 and (-4)^2 = 16, both 4 and -4 are square roots for 16. Ex
Rus_ich [418]

we can't say that "both square roots for 16, the area of the square, are the length of each side of the square"

Because one of these solutions does not have a meaning in the given contest.

<h3></h3><h3>Why is the statement incorrect?</h3>

So we have a square with an area of 16 square units, then the side length of that square will be given by:

S^2 = 16 square units

Now, there are two solutions for the above equation, these are:

S = 4 units

S = -4 units.

But being a solution of the equation does not mean that the solutions have sense in the context of the problem.

When we talk about dimensions of figures, negative numbers are not really well defined. We can't say that a square has a side length of "negative 4 units"

That does not make sense, remember that math is just a language, and it should be used to communicate things to others.

So the logical solutions (4 and -4) is not the only thing we need to look at when we state the solutions of a problem, but also the problem itself.

That is why we can't say that "both square roots for 16, the area of the square, are the length of each side of the square"

Because one of these solutions does not have a meaning in the given contest.

Find the length of the unknown side. Round your answer to the nearest whole number. (4 points)
balu736 [363]

Answer: 14 meters

Step-by-step explanation:

Use the pythagorean theorem to solve.

12 ² + 8 ²= c ²

208= c ²

√ 208 = √ c ²

14.42= c

UkoKoshka [18]

Answer:

Step-by-step explanation:

The ratio is 5:13 and the total number of candy is 18. If the total amount of candy increased by 40x then both candy values would increase by 40x. There are 200 Jolly ranchers and 520 jawbreakers.
