The radius of the base is 10 cm.
Solution:
Height of a cone = 15 cm
Volume of the cone = 1570 cm³
To find the radius of the base of the cone:
Volume of the cone = 
Divide by 15.7 on both side of the equation, we get
Taking square root on both sides of the equation, we get
⇒ r = 10
Hence the radius of the base is 10 cm.

Answer:
Step-by-step explanation:
(One tailed test at 5% significance level)
Sample size =200 and sample proportion =
Std error of p = 
Test statistic = p diff/std error = -2.89
p value = 0.001926
So we reject H0 and accept alternate hypothesis.
