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.

A.49.5 in^3
B.121.4 in^3
C.569.9 in^3
D.1024.4 in^3

Answer 1

C 
1/3(3.14) = 1.046666667
1.046666667*121=126.6466667
126.6466667*4.5=569.91
569.9 in^3

Answer 2

Volume =1/3× pi× radius^2×height
Volume=1/3×3.14×11^2×4.5
Volume=1/3×3.14×121×4.5
Volume=569.91
Hence, the Volume of the cone is 569.91 in^3
