Step-by-step explanation:
1/3 πr²h
Given
diameter (d) = 8ft
radius (r) = d/2 = 8/2 = 4 ft
height (h) = 3 ft
Volume of cone
=50.24 ft³
The standard deviation is 1 14.3-13.3 = 1 15.3-14.3 = 1

A.
when it's to the 0 power it equals 1
so therefore a=3
_______________
replace a with 3
divide 75 by 3 equalling 25
lastly find the square root
there fore
________
b= 5
a= 3
