At 11.5 pounds. candice buys a board that is 12 feet long. the store incorrectly measures and prices the board at 13.2 feet. lenny's bug collection has a bug that is 16 centimeters long. lenny fumbles with a ruler and incorrectly reports the bug to be 18 centimeters long.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
