Answer:
414.5 cm³
Step-by-step explanation:
The lateral area of a cylinder is given by the formula ...
LA = 2πrh
Then the radius is ...
r = LA/(2πh)
The volume of the cylinder is given by ...
V = πr²h
Using the above expression for r, this becomes ...
V = π(LA/(2πh))²h = LA²/(4πh)
V = (250 cm²)²/(4π·12 cm) ≈ 414.47 cm³
The volume of the cylinder is about 414.5 cm³.

Answer:
the answer is d because the numbers are multiples of eachother
Step-by-step explanation:
First, if the frame is square then it has equal-length sides. Find the measurement of the sides.
s² = 64
s = √64
s = 8
The first dimension is 8 × 8
Second, if the frame is rectangle, it would have length and width. For example the length is 16 inches.
w = 64/l
w = 64/16
w = 4
The second dimension is 16 × 4
There are more possibilities if the frame is rectangle, but i choose the simplest dimension.
So, the answers are 8 × 8 and 16 × 4
