Answer:
B)4.5 cubic feet
Step-by-step explanation:
To find the volume of a rectangular prism, we use the formula
V = l*w*h
V = 1.5*3*1
V = 4.5 ft^3
Equation for the area of a circle- π r²
The 2 radiuses are 6 and 9.
6 squared is 36 and 9 squared is 81.
The smaller one is 36π and the larger one is 81π.
The difference between them is the area of the shaded region.
81π - 36π = 45π
Use 3.14 for π.
45 x 3.14 = 141.3 u²
Hope this helps!
