A cone - shaped building has a height of 6 meters and a base with a diameter of 10 meters. The building will be filled with road
salt that costs $25 per cubic meter. How much will it cost to fill the building with road salt? Use 3.14 for π Round to the nearest hundredth HELP ME ASAP!!!!
The formula for the volume of a cone is .. V = (1/3)*π*r^2*h The radius (r) is half the diameter, so is 5 m. Fill in the numbers and do the arithmetic. .. V = (1/3)*3.14*(5 m)^2*(6 m) = 157 m^3
The cost will be $25 for each of those cubic meters, so is $25*157 = $3925.00.
