Awater tank is in the shape of a cylinder with the diameter of 29 feet and a height of 20 feet. the tank is 70% full. about how many gallons of water arein the tank? round your answer to the nearest whole number(1 ft 3 squared = 7.5 gal)

Aight, so you do base times height for the volume. the volume would be the tank at 100% capacity, right? What you do then is you can express the percent as a fraction, 7/10. Then, all that's left is divide by 10, multiply by 7. After that, you then just use your scale factor to convert cubic feet to gallons.
