Question

A cone has a radius of 11 inches and a height of 4.5 inches. What is the volume of the cone to the nearest tenth in³ ? Use 3.14 to approximate pi. 49.5 in³ 121.4 in³ 569.9 in³ 1024.4 in³

Answer 1

Volume of a cone can be found using the equation 1/3 π r² h (or π r² h / 3)
r = 11
h = 4.5
π ≈ 3.14
(1/3) (3.14) (11²) (4.5) = 
(1/3) (3.14) (121) (4.5) = 
(1/3) (3.14) (544.5) = 
(1/3) (1709.73) = 569.91

569.91 rounded to the nearest tenth is 569.9 so your answer would be 569.9 in³
