If 75% of a number is 300 and 20% of the same number is 80, find 95% of that number.

380

Step-by-step explanation:

380/400 is 95%

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 !
