Answer:
r≈2.82in
Step-by-step explanation:
Using the formula
V=πr2h
Solving forr
r=V
πh=75
π·3≈2.82095in
(4.3x10^3)^2
= 18.49 x 10^6
= 1.849 x 10^7
Hope this helps you!
aₙ= 4n+11
the sequence 15, 19, 23, 27
is AP with the first term 15 and
the common difference 19-15=23-19=27-23= 4
aₙ= a₁+(n-1)d
aₙ= 15+(n-1)*4= 15+4n- 4= 4n+11
