Answer:

A) 707 cm^3

Explanation:

In Given figure; we need to add volume of cylinder and volume of conical cylinder.

To find the volume, we do have different formula

For cylinder =пr^2 h

For conical cylinder= 1/3* пr^2 h

Now substituting value by identifying related radius and height

For cylinder = пr^2 h =3.14*5^2*7 =549.5 cm^3

For Conical cylinder = 1/3* пr^2 h=4/3*3.14*5^2*6=157 cm^2

Total volume of composite solid=volume of (cylinder+conical ) cylinder

=549.5 cm^3+157 cm^2=706.5cm^3 is equal to A) 707 cm^3
