Hello there! :-)
The formula for finding the area of a circle is
Notice that only the radius is squared.
We are given the radius of the circle: 21 cm.
We plug the value of r into the formula:
- A=π(21)²
- A=π(441)
- A=1,385 cm
Hope this helps. Use the comment section to clarify your doubts.

Good luck.
The formula to find the volume of a prism is V=Bh (Volume = Base x height). Let's plug in the dimensions you were given:
V=Bh
V=(5)(10)
V=50 {tex] ft^{2} [/tex]
To find the new volume of the dilated prism, cube the dilated factor, then multiply by the volume you just found (old volume):
New Volume = (
)(Old Volume)
V = (
)³·50
V = (
V = 86.4
V=Bh
V=(5)(10)
V=50 {tex] ft^{2} [/tex]
