Question

Which expression represents the volume, in cubic units, of

the composite figure?
O (52)(13) - 1 (52)(12)
07(52)(13) – 1 (52)(25)
(52)(13) + (52)(12)
T(52)(13) + (52)(25)

Answer 1

c

Step-by-step explanation:

I'm not writing all that

Answer 2

C. π(5²)13 + 1/3π(5²)12 cubic units

Step-by-step explanation:

The composite figure is made up of a cylinder and a cone.

The volume of the composite figure = volume of the cylinder + volume of the cone

For the CYLINDER:

Volume = πr²h

h = height of the cylinder = 13units

r = radius of the cylinder = 5units

Volume = π(5²)13 cubic units

For the CONE:

Volume of a cone = 1/3πr²h

height of the cone = 25-13 = 12units

Radius of the cone = radius of the cylinder = 5units

Volume = 1/3π(5²)12 cubic units

Volume of the composite figure will give: π(5²)13 + 1/3π(5²)12 cubic units
