A mirror frame in the shape of an oval is shown below. The ends of the frame form semicircles:
An oval is formed by a rectangle with semicircles at each end. The length of the rectangle is 54 inches. The width of the rectangle is 27 inches.

Which of the following is the perimeter of the inner edge of the frame?

(π = 3.14)

192.78 inches
246.78 inches
277.56 inches
331.56 inches

please help lol

Answer 1

Answer:

The answer is 192.78 inches

Step-by-step explanation:

An oval is formed by a rectangle with semicircles at each end. We can visualize this easily.

The length of the rectangle is 54 inches.

The width of the rectangle is 27 inches.

The perimeter of rectangle is =

= 162 inches

And because there are two semicircles, we can combine them to form a circle. So, perimeter of a circle is called a circumference.

The width of the rectangle forms the diameter, so its half will be the radius.

r =

The circumference is given by :

= inches

Now as the described oval shape is a complete figure without lines inside, we will subtract the width of both sides of the rectangle from the complete perimeter.

The complete perimeter is = inches

The inner edge perimeter will be = = 192.78 inches

Find the radius of the circle.
Circumference = 18.84 yd
a. 3 yd
b. 59.16 yd
c. 6 yd
d. 118.32 yd

what's the answer??

Answers

Answer:

A. 3yd

Step-by-step explanation:

There are two formulas that can be used for the circumference of a circle:

c = πd and c = 2πr

Since we want to solve for the radius, let's use c = 2πr

The circumference, 'c', is 18.84 inches

Since 'π' is an irrational number, we use its approximation of 3.14

We are trying to solve for 'r', which is the radius

The circumference, 'c', is 18.84 inches

Since 'π' is an irrational number, we use its approximation of 3.14

We are trying to solve for 'r', which is the radius

Plugging in, we get:

18.84 = 2(3.14)r

Since 'π' is an irrational number, we use its approximation of 3.14

Notice there are the same amount of decimal places (two!) in the answer as the combined amount of spaces in the numbers being multiplied!

18.84 = 6.28r

The goal is to isolate and solve for 'r', which is the radius

18.84/6.28 = 3

So we get "3 = r", which means the radius is 3 inches!

Find the mean, median mode and range of: 75, 80, 60, 90, 85, 80, -7, 90, 70, 65

Answers

Answer:

Mean: 68.8.

Median: 77.5

Mode: 80, 90

Step-by-step explanation:

-7 + 60 + 65 + 70 + 75 + 80 + 80 + 85 + 90 + 90 = 688. Then divide by 10 because there are 10 numbers.

-7 + 60 + 65 + 70 + 75 + 80 + 80 + 85 + 90 + 90

(75, 80) are the middle numbers, so add them both, then divide by 2.

80, 90 appear more than the other numbers.

Range is highest - lowest. 90 - (-7) = 97, or it could be 83. I don't know.

The mean is 68.8

The median is 77.5

The mode is 80 and 90

The range is 97

(adding more to this but since the question only asked for one answer this should be enough!)

Step-by-step explanation:

a : 59

b : 59

c : 121

d : 121

f : 59

g : 90

h : 59

j : 31

k : 31 (everything in bold is uncited knowledge from me doing this years ago :,)

m : 90

so g must = 90 because not only is it in a right triangle, but also the corner of the rectangle. this goes for hk, m and jf, they all must add up to 90.

given a = 59 we can also find d from this, as it must add up to 180.

then adding g [90] + a [59] we get 149, which we then subtract from 180 to get j.

we get 31 from that and can now subtract 90 from that to find f, which is also 59, so f=59.
