Answer:

100(pie) in^3

Step-by-step explanation:

a^2 +b^2=c^2 =5^2+b^2=13^2 b^2=squre root 144 b=12 hight=12

I was just finding the hight by finding the other side of the trinagle

v=1/3(pie r^2)(h)

v=1/3(25)(12) I don't multiply by pie becuase of the qetions

v=100(pie) in^3

I got it right on the test

Answer:

to find the answer you have to multiply pie by the radius squared and then multiply that by the height and divide by 3. Im sorry i couldn't do that because you did not provide the height.

A person whose eye level is 15 feet above the ground is looking at a building. The angle of elevation to the top of the building
uysha [10]

Answer:

61.97 feets

Step-by-step explanation:

Using trigonometry :

Horizontal distance between the person and building,

Let distance = d

Tan 15 = 15 / d

0.2679491 * d = 15

d = 15 / 0.2679491

d = 55.980781

To obtain the height, h :

tan 40 = (h-15)/d

d = 55.98

h-15 = 55.98 (tan 40°)

h - 15 = 55.98 * 0.8390996

h - 15 = 46.972797

h = 46.972797 + 15

h = 61.972797

h = 61.97 feets

Perry made $34,885 this year. If the inflation rate was 6.5 percent, how much was his salary actually worth? (purchasing power)
Allushta [10]
<h3>The salary of Perry if inflation is 6.5 % is $ 32617.475</h3>

<em><u>Solution:</u></em>

Given that,

Perry made $34,885 this year

The inflation rate was 6.5 percent

To find: Salary worth if inflation rate was 6.5 percent

From given,

Inflation rate = 6.5%

Therefore,

Worth of salary due to inflation = 100 % - 6.5 % = 93.5 %

Money earned in this year by Perry = $ 34, 885

Therefore,

Worth of Perry salary due to inflation = 34,885 x 93.5%

\text{Worth of Perry salary due to inflation }= 34885 \times \frac{93.5}{100}\\\\\text{Worth of Perry salary due to inflation }= 34885 \times 0.935\\\\\text{Worth of Perry salary due to inflation }= 32617.475

Thus the salary of Perry if inflation is 6.5 % is $ 32617.475
