Answer:

21.5 cm² (nearest tenth)

Step-by-step explanation:

To find the shaded region, subtract the area of the circle from the area of the square.

Square

Area of the square = 10² = 100 cm²

Circle

Given diameter of circle = 10 cm

⇒ radius = 10 ÷ 2 = 5 cm

⇒ Area of the circle = π · 5² = 25π cm²

Area of shaded region

= area of square - area of circle

= 100 - 25π

= 21.46018366...

= 21.5 cm² (nearest tenth)                                  

Answer:

So first, we figure out the maximum the patient could be taking each day: 2 tabs every 4 hours = 12 tabs per day at the most.

Step-by-step explanation:

It's 4/5 as a reduced fraction.

Perimeter is the combined ammount of all the sides added together.

For example, if a square has sides of 4, it would be 16 because 4+4+4+4 = 16 units.

Answer:

Perimeter is the total distance around the outside of a shape.

Step-by-step explanation:

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications. A calculated perimeter is the length of fence required to surround a yard or garden. The perimeter of a wheel/circle (its circumference) describes how far it will roll in one revolution. Similarly, the amount of string wound around a spool is related to the spool's perimeter; if the length of the string was exact, it would equal the perimeter.

Answer:

infinite solutions

Step-by-step explanation:

Hey there!

In order to solve this problem, we need to first distribute the [tex](x+4)(x-4)[/tex]

This is equal to [tex]x^2-16[/tex]

Now we can combine like terms

[tex]x^2[/tex] and [tex]-x^2[/tex] cancel out

also

[tex]16[/tex] and [tex]-16[/tex] cancel out

The equation ends up as 0 = 0

So the answer to this answer is infinite solutions

The division is one of the four fundamental arithmetic operations. The filling that Camilo uses in each tray is 10.667 ounces.

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

The total filling that was available with Camilo is 32 ounces, which he put in three different trays equally. Therefore, the filling available in each tray is equal to,

[tex]\rm \text{Filling in each tray} = \dfrac{\text{Total Filling}}{\text{Number of tray}}\\\\\text{Filling in each tray} = \dfrac{32\ ounces}{3} = 10.667 ounces[/tex]

Hence, the filling that Camilo uses in each tray is 10.667 ounces.

Formulae

(where r is the radius of the circle)

The railing of the circular fountain is the circumference of a circle.

The area of the fountain is the area of a circle.

First, find the radius by using the circumference formula:

Given:

[tex]\implies 132=2 \pi r[/tex]

[tex]\implies r=\dfrac{132}{2 \pi}=\dfrac{66}{\pi}[/tex]

Now input the found value of r into the formula for the area of a circle:

[tex]\begin{aligned}\implies \textsf{Area} & =\pi \left(\dfrac{66}{\pi}\right)^2\\\\ & = \dfrac{4356}{\pi}\\\\ & = \dfrac{4356}{3.14}\\\\ & = 1387.261146...\\\\ & = 1387.3 \: \sf ft^2\:(nearest\:tenth)\end{aligned}[/tex]

The triangle is rotated about an axis then it creates a cone and the approximate circumference of the base is 63 mm. Then the correct option is C.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The equilateral triangle shown is rotated about line a.

Each side of the triangle measures 20 mm.

If the triangle is rotated about an axis then it creates a cone.

Then the radius of the cone will be

[tex]\rm r = \dfrac{20}{2} = 10 \ mm[/tex]

Then the height of the cone will be

[tex]\rm h = 20 \sin 60^o\\\\h = 17.32 \ mm[/tex]

Then the circumference of the base circle will be given as

[tex]\rm Circumference = 2 \pi r\\\\Circumference = 2 \pi \times 10\\\\Circumference = 62.8318 \approx 63 \ mm[/tex]

Answer:

64π or 200.96

Step-by-step explanation:

The area of a circle is [tex]\pi r^2[/tex]. The radius of the circle is half the diameter, which is 16/2 = 8. The area of the circle is 64π.

Answer:

64π = area
200.96 = area

Step-by-step explanation:

Diameter = radius * 2

16 = 2r

radius = 8

Radius^2 * π = area

8^2 * π = area

64π = area

64*3.14 = area

200.96 = area

Answer:

[tex]A_{total} = 217\ cm^2[/tex]

Step-by-step explanation:

Step 1:  Determine the area of the bottom rectangle

[tex]A = l * w[/tex]

[tex]A = 14\ cm * 11\ cm[/tex]

[tex]A = 154\ cm^2[/tex]

Step 2:  Determine the area of the top rectangle

[tex]A = l * w[/tex]

[tex]A = 7\ cm * (20\ cm - 11\ cm)[/tex]

[tex]A = 7\ cm * 9\ cm[/tex]

[tex]A = 63\ cm^2[/tex]

Step 3:  Determine the total area

[tex]A_{total} = 154\ cm^2 + 63\ cm^2[/tex]

[tex]A_{total} = 217\ cm^2[/tex]

Answer:  [tex]A_{total} = 217\ cm^2[/tex]
