In rectangle PQRS, PR = 11x – 20and QS = x + 160.
Find the value of x and the length of each diagonal.
(unit 7)

Step-by-step explanation:

1. Value of x

The diagonals of a rectangle are equal, so

PR = QS

2. Length of each diagonal

PR = 11x - 20 = 11×18 - 20 = 198 - 20 = 178

QS = x + 160 = 18 + 160 = 178

The length of each diagonal is 178.

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 !
