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

Verified Answer :

C 
1/3(3.14) = 1.046666667
1.046666667121=126.6466667
126.6466667
4.5=569.91
569.9 in^3

Setor9

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
