Step-by-step explanation:
we know that
The lateral area of a cone is equal to

where
r is the radius of the base
l is the slant height
we have


assume 
substitute the values

This value is an underestimate, because the assumed pi value is less than the real value

Answer:
The line represents a direct variation function.
Step-by-step explanation:
This line would cross the point (0, 0) making it a direct variation function.
We know the line would cross (0, 0) because the slope of the line is 2/3 (change in y over change in x, so 4-2 over 6-3 which simplifies to 2/3). From the point (3, 2), we can use the slope to calculate backwards to the origin.
Answer:

Step-by-step explanation:
Let number of pounds of cans collected by Amy = 
Let number of pounds of cans collected by Bruce = 
Let number of pounds of cans collected by Carlos = 
As per question statement, total number of cans collected = 168
..... (1)
Number of pounds collected by Bruce is
rd of the pounds of cans collected by Carlos.

Number of pounds collected by Amy is equal to number of pounds collected by Bruce and Carlos combined.
Using equation (2):

Using equations (2) and (3) in equation (1), we get:

Using equation (2):
