Answer:
didn't u already answer this already
and which question do you need help on
Step-by-step explanation:
Answer:
The answer to your question is Volume = 27.5 ft³
Step-by-step explanation:
Data
Volume = ?
height = 3.9 ft
Circumference = 16.3 ft
Process
1.- Calculate the radius of the Cone
Circumference = 2πr = 16.3 ft
-Solve for r
r = 16.3/2π
r = 16.3/6.28
r = 2.5955 ft
2.- Calculate the volume
Volume = 1/3πr²h
-Substitution
Volume = 1/3(3.14)(2.5955)²(3.9)
-Simplification
Volume = 1/3(82.4966)
-Result
Volume = 27.5 ft³
Subtract.
596 3/5 - (-81.8) [81.8 is below sea level so it is negative]
566.6 + 81.8 [Convert to decimal and distribute negative]
= 678.4 feet
A
The volume (V) of a pyramid is found using the formula
V = 
× area of base × height(h)
area of base = 9² = 81 ← area of a square, hence
324 = × 81 × h = 27h ( divide both sides by 27 )
h = 
= 12 → A
Answer: a) 3 2/3, b) 5 2/5
Explanation:
a) 5/3 + 6/3 = 11/3 = 3 2/3
b) 12/5 + 15/5 = 27/5 = 5 2/5
