What is the length of AD?

So, We Need To Write An Equation To Find This:

AD = lAl + lDl Step-by-step explanation:

AD = l-7l + l8l

l-7l= 7.

AD = 7 + 8

7+8 = 15

AD = 15 So, AD = 15. This Means That The Answer Is B.

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 !
