Acompany that manufactures storage bins for grains made a drawing of a silo. the silo has a conical base, as shown below. the figure shows a silo shaped as a closed cylinder with a conical end. the diameter of the silo is 4 ft, the length of the cylindrical part is 10 ft, and the entire length of the silo is 13 ft.. what is the total volume of grains that can be stored in the silo?

There are 2 shapes formed in the figure. A cone and a cylinder. We simply need to get each volume and add it up to get the total volume of grains that can be stored in the silo.

Volume of a cone = π r² h/3
V = 3.14 * (2ft)² * 3ft/3
V = 3.14 * 4ft² * 1ft
V = 12.56 ft³

Volume of a cylinder = π r² h
V = 3.14 * (2ft)² * 10ft
V = 3.14 * 4ft² * 10ft
V = 125.6 ft³

12.56 ft³ + 125.6 ft³ = 138.16 ft³  Total volume of grains that can be stored in the silo.

a - base

b - exponent

so,

the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8
