Question

*ANSWER PLEASE, DIFFICULT QUESTION* A toy rocket is a composite of a cylindrical body with a cone for a nose. Find the volume of the rocket if the radius of the base is 1.25 inches, the height of the tip is 3 inches, and the height of the entire rocket is 15 inches. a.) 63.8 in3 b.) 56.3 in3 c.) 176.6 in3 d.) 58.9 in3

Answer 1

63.8 in

Explanation:

the formula of te volume of the cone is : πr²h/3

the height of te cone is the height of the tip

V=π(1.25)² * 3/3

V1=4.91( rounded to the nearest hundredth)

volume of the cylinder =πr²h ( the height of cylinder=25-3=23)

V2=π(1.25)²*12

V2=58.90

V1+V2=4.91 +58.90=63.81 ≅63.8

Answer 2

a) 63.8 in³

Explanation:

so the cylinder is 12 inches high

πr²h = π(1.25)²(12) = 58.90 in³

cone is 3 inches high

1/3πr²h = = 1/3π(1.25)²(3) = 4.91 in³

58.90 + 4.91 = 63.81 in³
