Answer:
3142.86 cubic cm
Step-by-step explanation:
volume of cone is given by formula
volume of cone = 1/3(area of base*height)
Given radius of base = 10cm
we know area of circle is given by 
where r is radius of circle
thus area of base of cone is calculated below
area of base of cone is 314.2857 square cm
height = 30 cm
Thus volume of cone = 1/3* (area of base*height)
= 1/3(314.2857*30)
= 1/3 *9428.571 = 3142.857.
Thus, volume of cone is 3142.857 cubic cm.
volume of cone to the nearest hundredth is 3142.86 cubic cm

Answer:
The correct option is B
Step-by-step explanation:
From the question we are told that
The null hypothesis is 
The alternative hypothesis is 
The p-value is 
The level of significance is 
From the given values 
so we fail to reject the null hypothesis
So there is NOT sufficient evidence to conclude the proportion of work time linguists study a new language is more than 10%.
