Answer:
226.9 in²
Step-by-step explanation:
The formula for circumference of a circle is:
C = 2πr, where π = 3.14 and r = the radius
The formula for area of a circle is
A = πr²
First, using the formula for circumference, you can solve for 'r':
53.42 = 2πr or 53.42 = 6.28r (divide) r = 8.5
Now, use the value of 'r' to solve for area:
A = π8.5² or 3.14(8.5)² = 226.9 in²

Answer:
466 ![cm^{3}](https://tex.z-dn.net/?f=cm%5E%7B3%7D)
Step-by-step explanation:
Ok to solve this problem we need to find the volume of the rectangular prism and subtract the volume of the cube from it.
The volume of the rectangular prism is Length * Width * Height.
L = 15
W = 9
H = 4
15 * 9 * 4 = 530 ![cm^{3}](https://tex.z-dn.net/?f=cm%5E%7B3%7D)
The volume of the cube is ![l^{3}](https://tex.z-dn.net/?f=l%5E%7B3%7D)
= 4
4^3 = 64
530-64 = 466 cm^3
