Add the opposite of 4 so basically -4. Hope this helps
N + (n+1) + (n+2) + (n+3) = 90
if n is the first number, then the next number is 1 more than n, the next number is 2 more than n, etc.
Simplify the above expression:
4n + 6 = 90
4n = 84
n = 21
n+1= 22
n+2 = 23
n+3 = 24
It’s $24 :) !!!!!!!!!!!!!!!!!!!!!!
V=(4/3)pir^3
36pi=v
36pi=(4/3)pir^3
divide both sides by pi
36=(4/3)r^3
multiply both sides by 3/4 to clear fraction (4/3 times 3/4=12/12=1)
108/4=r^3
27=r^3
cube root both sides
3=r
radius=3ft
