I plugged it in to a truncated square pyramid calculator and got v=76
the formula for this shape is V=1/3(A squared+AB+B squared)H.
Your answer is A have a good day
radius = 3 feet
rearrange the formula making r the subject
πr³ = V ( multiply both sides by 3 to eliminate fraction )
4πr³ = 3V ( divide both sides by 4π )
r³ =
= ( 3 × 36π ) / 4π = 3 × 9 = 27
take the cube root of both sides
r =
= 3
