First, area of large circle(A1)= pie×R^2
=3.14×(3+4)^2=3.14×49=154 sq. cm
area of small circle (A2) pie× r^2
=3.14×3^2=28.27 sq.cm
now
area of shaded region= (A1-A2)/3
=(154-28.27)/3
=125.73/3
=41.91 sq. cm
Answer:

Step-by-step explanation:
Volume of a cylinder = pi r^2 h If the cone has exactly the same measurements then its formula is going to be
V_cone = 1/3 pi r^2 h. If that's the case the only difference is that the Cone's volume is 1/3 that of the cylinder
V_cone = 1/3 V_cylinder
V_cone = 1/3 136 cubic cm.
V_cone = 45.33 cubic cm.
