Answer:
The volume of the cone is
Step-by-step explanation:
The given cone has a radius of 10 cm and and height of 9 cm.
The volume of a cone is given by:
We substitute r=10 and h=9 , to obtain:
Simplify exponents to get:
Simplify:
Therefore the volume of the cone is
Answer:
Option B k > 0
Step-by-step explanation:
we know that
Observing the graph
The slope of the line is positive
The y-intercept is negative
we have
The slope of the line is equal to
Remember that the slope must be positive
so
The value of k is greater than -2/5
Analyze the y-intercept
1.5 is greater than zero
so
the solution for k is the interval ------> (1.5,∞)
therefore
must be true
k > 0
