Find the area of a semi circle with a diameter of 28cm

Mathematics
1 answer:
Alexandra [31]2 years ago
8 0

since it has a diameter of 28, then its radius must be half that or 14.

\textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=14 \end{cases}\implies A=\pi (14)^2\implies A=196\pi ~\hfill \stackrel{\stackrel{semi-circle}{half~that}}{98\pi }

here is the image of triangle ABC and its dilation using Center D and scale factor 2. Why is B'C' on the same line as its corres
GaryK [48]

Since only the lengths increase by scale factor,  B'C' on the same line as its corresponding side segment BC​ .

<u>What is the Dilation?</u>

Math definition of dilation Resizing an object is accomplished through a change called dilation. The objects can be enlarged or shrunk via dilation. A shape identical to the source image is created by this transformation. The size of the form does, however, differ.

The following are the properties of dilation of the triangle:

1)measures of the angles will not change

2)The sides  of the image of the triangle are multiplied  by the scale factor 2.

So,

A'B'=2AB

B'C'=2BC

A'C'=2AC

Since only the lengths  increase by scale factor,  B'C' on the same line as its corresponding side segment BC​ .

How can you tell when a pattern shows counting on by tens?
s2008m [1.1K]
Counting by Tens with numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 Counting by Tens with words ten, twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety, one hundred Number Patterns when counting by Tens When you count by tens the numbers create a pattern. All the numbers end with a zero. The first digits are just like the numbers when you count (1, 2, 3, 4, 5, etc.). This pattern gives the numbers 10, 20, 30, 40, 50, etc. found from: http://www.aaamath.com/k4c_cox1.htm

Noah is running a portion of a marathon at a constant speed of 6 mph. Complete the table to predict how long it would take him t
ycow [4]

Answer:

\begin{array}{cc}\text{Time}&\text{Distance}\\ \\1&6\\ \\\dfrac{1}{2}&3\\ \\1\dfrac{1}{3}&8\\ \\1\dfrac{1}{2}&9\\ \\9&54\\ \\4\dfrac{1}{2}&27\end{array}

Step-by-step explanation:

Noah's running speed = 6 mph.

Use formula D=v\cdot t, where

D is the distance,

v is the speed,

t is the time.

If t=1 hour, then D=6\cdot 1=6 miles.

If t=\dfrac{1}{2} hour, then D=6\cdot \dfrac{1}{2}=3 miles.

If t=1\dfrac{1}{3} hours, then D=6\cdot 1\dfrac{1}{3}=6\cdot \dfrac{4}{3}=8 miles.

If t=1\dfrac{1}{2} hours, then D=6\cdot 1\dfrac{1}{2}=6\cdot \dfrac{3}{2}=9 miles.

If t=9 hours, then D=6\cdot 9=54 miles.

If t=4\dfrac{1}{2} hours, then D=6\cdot 4\dfrac{1}{2}=6\cdot \dfrac{9}{2}=27 miles.

So, the table is

\begin{array}{cc}\text{Time}&\text{Distance}\\ \\1&6\\ \\\dfrac{1}{2}&3\\ \\1\dfrac{1}{3}&8\\ \\1\dfrac{1}{2}&9\\ \\9&54\\ \\4\dfrac{1}{2}&27\end{array}
