The volume of a cylindrical container is 157 cubic inches. The height of the container is 2 inches. Find the radius of the container. Round your
answer to the nearest whole number?

Step-by-step explanation:

h = 2 in ,    V = 157 in³

V = π r² × h

157 = π r² × 2

157 = 2π × r²

step-by-step explanation:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
