A storage tank has a height of 10 feet and a radius of 3 feet. The tank is 1/4 full of oil. How much oil in cubic feet is currently in the cylindrical tank? Leave in terms of pi

the volume of the oil is the base times the height. in this case the base is the areas of the circle.
r squared times π is the area of a circle. therefore, the area of this circle is 9π
the height is 10*1/4=2.5ft
2.5*9π= 22.5π
