Step-by-step explanation:
2(5) - 4(1) +3 =9
10 - 4 +3 = 9
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
