27 is 30 % of what number? Whole

90

Step-by-step explanation:

27 = 30%

Multiply both sides by 3:

81 = 90%

We need 10% more to get 100%, so since 27 is 30%, you need to divide 27 by 3 to get 10%:

9 = 10%

Add it to the previous equation:

90 = 100%

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 !
