N is a whole number
2n is greater than 20
5n is less than 60
what is the value of n?

Step-by-step explanation:

S.S{11} because if it is not 11 the statement will be false

Step-by-step explanation:

2n =20

n=10

but 2n is greater than 20 and 5n less than 60 so n is 11

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

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 !
