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
