Find the area of the shaded rectangle and then the second. Subtract them from eachither giving you the proper area of the shade grey rectangle
Answer:
263.76
Step-by-step explanation:
To answer this question, we need to know the equation for surface area of a cylinder which can be given as Surface Area=2*pi*
+2*pi*R*H, where R is the radius of the cylinder (also can be calculated as Diameter/2=6/2=3) and H is the height of the cylinder which is given as 11. Considering pi=3.14, the surface area of the cylinder can now be calculated as 2*3.14*
+2*3.14*3*11=263.76.
3k + 10 = 22
3k = 22-10
3k = 12
k = 12/3
k = 4
