Step-by-step explanation:

From 3),

Consider A(2,2). From 3),

Consider A(2,1). From 3),

Form 2),

Then

Then

Hence,

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 !

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
