Question

*PLEASE ANSWER THANK YOU* 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.) 176.6 in3 b.) 56.3 in3 c.) 58.9 in3 d.) 63.8 in3

Answer 1

63.8 in3

Explanation:

Answer 2

Volume of toy = 63.8 in² (Approx)

Explanation:

Given:

Height of cone (h) = 3 in

Height of cylinder (H) = 15 - 3 = 12 in

Radius (r) = 1.25

Find:

Volume of toy

Computation:

Volume of cylinder = πr²H

Volume of cylinder = (22/7)(1.25)(1.25)(12)

Volume of cylinder = 58.92 in²

Volume of cone = (1/3)πr²h

Volume of cone = (1/3)(22/7)(1.25)(1.25)(3)

Volume of cone = 4.91 in²

Volume of toy = Volume of cylinder + Volume of cone

Volume of toy = 58.92 in² + 4.91 in²

Volume of toy = 63.8 in² (Approx)
