For this case, the first thing you should do is apply the following formula:
V = (pi * r ^ 2 * h) / (3)
Where,
r: radio
h: height
Substituting values we have:
V = (3.14 * (9 ^ 2) * 2) / (3)
V = 169.56
Rounding:
V = 169.6 units ^ 3
Answer:
the volume of the cone is:
B. 169.6 units cubed
Answer:
(2,-3)
Step-by-step explanation:
The intersection point of y=x-5 and y=-3x+3 is (2,-3) on a graph.
The time for the job for which the two company are the same is 16
<h3>How to form the equation and find the cost?</h3>
A yard cleanup service charges a $345 fee plus $16.25 per hour. Therefore,
using linear equation,
y = mx + c
where
Therefore,
y = 345 + 16.25x
Another cleanup service charges a $213 fee plus $24.50 per hour. Therefore,
y = 213 + 24.50x
Hence, the time when both cost are the same is as follows;
213 + 24.50x = 345 + 16.25x
213 - 345 = 16.25x - 24.50x
-132 = -8.25x
x = 132 / 8.25
x = 16
