Q:
PLEASE HELP!!!!! I HAVE A DEADLINE !!!!Bob built a rocket that has a radius of 2 feet. Find the volume of the whole rocket he built. Round your answer to the nearest tenth. Show all of your work!!!
Accepted Solution
A:
Answer:V_rocket = 44[tex]\pi[/tex] ft^3 = 138.2 ft^3Step-by-step explanation:Volume of coneV_cone = (1/3)*([tex]\pi[/tex]*(radius^2))*hradius = 2fth = height of the cone = 3 ftpi = 3.1416V_cone = 4[tex]\pi[/tex] ft^3Volume cylinderV_cylin = ([tex]\pi[/tex]*(radius^2))*h_cylh_cyl = height of the cylinder = 10 ftV_cylin = 40[tex]\pi[/tex] ft^3Volume rocketV_rocket = V_cone + V_cylin = 4[tex]\pi[/tex] ft^3 + 40[tex]\pi[/tex] ft^3V_rocket = 44[tex]\pi[/tex] ft^3 = 138.2 ft^3
