EASY A silo casts a shadow that is 99 feet long. Next to the silo is an 18-foot-tall barn that casts a shadow that is 13.5 feet long. How tall is the silo?

74.24ft tall, you were right!

Step-by-step explanation:

13.5/18 = 0.75

This is the ratio of shadow by actual height that you will use to find the height of the silo so now you multiply:

99*0.75 = 74.25

74.25 is the exact measurement of the taller silo's height.

i dont know

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 !
