Answer with Step-by-step explanation:

A scale model of a school building is 5 inches tall.

Actual size of the school building is 100 feet.

1 feet=12 inches

100 feet=12×100 inches

             = 1200 inches

5 inch is representing 1200 inches

1 inch represents  1200/5 inches

1 inch represents  240 inches

or  1 inch represents  12×20 inch

or 1 inch represents 20 feet

Scale of the model is:

1 inch represents  240 inches

1 inch represents 20 feet

a) 15/7

step-by-step explanation:

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 !
