The volume of a cylinder is 20ft3. Which expression represents the volume of a cone with the same base and height as the cylinder?

Volume of Cone = 20 / 3 ft³

Step-by-step explanation:

Volume of cylinder = πr²h

Volume of cone with same base & ht = πr²h/3

Given, πr²h = 20

Vol. of cone = 20/3 ft³

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:
