A cone has a height of 7ft and a radius of 4ft which equation can find the volume of the cone v=1.3 (7.2)
1 answer:
Answer:
The volume of a cone is:
V=(hπr^2)/3, where h=height and r=radius
V=(7π4^2)/3
V=112π/3 ft^3
V≈117.29 ft^3 (to nearest hundredth of a cubic foot)

Answer:
Step-by-step explanation:
d = 2r => r = d/2 = 16in/2 = 8 inches
V = Ab×h
= π·r²×h
= 3.14·(8in)²×5in
= 1004.8 in³
1 foot = 12 inches
divide 69 by 12
69/12 = 5.75 feet
