Ineed ! select all radical expressions that are equivalent to 5 2/3. 15−−√ 52−−√3 (5√3)2 10−−√3

Just for the people in the future this is what my test said for the answers, hope it helps.

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 !
