In this discussion, you have the opportunity to have some hands-on fun. With a
tape measure determine the diameter and circumference of at least three circular
objects. Calculate the ratio of the circumference to the diameter.
Take a look at Khianna's post:
I used a tape measure to determine the diameter and circumference of an orange
juice can, a trash can, and a lamp shade. Here is what I found:
Circumference
4.65 in
Ratio
3.1
OJ Can
Diameter
1.5 in
8 in
6 in
Trash Can
3.12
24.96 in
18.8 in
Lamp Shade
3.13
The ratio was close to Pi, but never actually equaled 3.14, maybe because of an
error when I measured the objects.
After you complete your measurements, use the diameter to calculate the exact
circumference of each object as shown on the next page.
Use the diameter to calculate the exact.value of the circumference of each object.
Look how Khianna added to her post:

Setup

Using the given formula with the relevant values, we have ...

You are a waiter at a restaurant. A family had a bill of $116.17. They leave you a 20% tip. How much of a tip did you get?

Answers

Answer:

Hello there! :) The tip they would leave you would be of $23.23

Step-by-step explanation:

The first step is to devide 116.17 by 100, which would equal 1.1617, which is obviously not your answer or a valid amount of money. But, you now take this 1.1617 by 20. Why? Becuase 20% is the same as 20 out of 100. Now you multiply 1.1617 × 20 and you will get $23.23.

Example on how to solve:


To figure out the tip, you need to find 20% of $52.60.
0.2×52.6=10.52
You should leave $10.52 for the waiter if you want to leave him exactly 20%.

To figure the tax, you need to find 8% of $52.60.
0.08×52.6=4.208
Next, add them up:
52.6+10.52+4.208=67.328
The total bill, including tax and tip, will be $67.33.

A. less than 7 cm
B. between 7 cm and 8 cm
C. between 8 cm and 9 cm
D. greater than 9 cm

2. The net below shows equilateral triangles. What is the total surface area of the triangular pyramid in square feet?

Answers

Answer:

65^2

Step-by-step explanation:

if you woulndt mind giving me brainliest im trying to rank up, only if u dont mind.

#1:

Between 8 cm and 9 cm

Work:

SA = 6s^2  

390 = 6 s^2

390/6 = 6s^2 /6

65 = s^2

sqrt(65) = s

s = 8.06

#2:

The total surface area of the triangular pyramid is 107 * square feet.

What is a triangular pyramid?

Take a triangle. This is a base. Now take 3 triangles such that each of them are connected to one-one side of the first triangle and when they're taken together, they form a closed object, called as a triangular pyramid.

We are given that;

The length of median from outer triangle to side of the inner triangle is 8 ft

Side of inner equilateral triangle is 12 ft

Now,

First, we can find the height of the outer equilateral triangle using the Pythagorean theorem:

a is half the length of the side of the inner triangle (6 ft), m is the length of the median (8 ft), and b is the length of the side of the outer triangle (unknown).

a^2 + (m/2)^2 = b^2

b^2 = 6^2 + 8^2/4

b^2 = 36 + 4

b^2 = 40

b = sqrt(40)

b = 2 * sqrt(10)

So the height of the outer triangle is:

h = b * sqrt(3)/2

h = sqrt(30)

Now we can find the area of each equilateral triangle using the formula:

A = (sqrt(3)/4) * s^2

For the inner triangle:

A_inner = (sqrt(3)/4) * 12^2

A_inner = 36 * sqrt(3)

For the outer triangle:

Now we can find the area of the base, which is just the area of the inner equilateral triangle:

A_base = A_inner

A_base = 36 *

Finally, we can find the surface area of the triangular pyramid by adding the areas of the four triangles and the base:

SA = A_inner + 3 * A_outer + A_base
