Volume of a cone=1/3 times height times area of base
area of base=area of circle=pi times r^2
r=3
aprox pi to 3.14
height=9
so we have
volume=1/3 times 9 times 3.14 times 3^2
3^2=9
1/3 times 9 times 3.14 times 9
3 times 3.14 time s9
9.42 times 9
84.78
nearest tenth
0.78=0.8
answer is 84.8 ft^3
Step-by-step explanation:

Angle C must = [180 - 73 - 57 ] = [180 - 130] = 50°
And using rhw Law if Sines, we have.....
AB/sin C = AC/sin B → 24/sin(50) = AC/sin(73) → AC = 24*sin(73)/sin(50) = about 29.96 in
The number of potential customers that the company has reached is 10,000 e--mail addresses.
<h3>What is a word problem in mathematics?</h3>
A word problem is a real-life problem and it can be approached with the use of a mathematical model, interpretation into variables, and arithmetic operations usage.
Given that:
- A company buys three mailing lists with 2500, 3500, and 4000 addresses respectively.
The number of potential customers that the company has reached is:
= 2500 3500 + 4000 e--mail addresses.
= 10,000 e--mail addresses.
