No number times itself can equal 26.
A perfect square example is 36, where 6 and 6 multiplied by each other can equal, you know, 36.

Answer:
Because it had more cents
Step-by-step explanation:
Final answer:
The question is an example involving principles of physics, specifically force, mass and motion. The quarter didn't roll down the hill with the nickel because it is heavier and requires more force to overcome static friction. Factors such as coin's mass, hill's slope, and gravity play a role in determining whether an object will roll down a slope.
Explanation:
Whether a quarter or a nickel would roll down the hill depends on a combination of the coin's mass and the slope of the hill. Because a quarter is heavier than a nickel, it requires more force to overcome static friction to start its roll than a nickel would. So if the hill is not steep enough, the quarter, due to its larger mass, might not roll whereas the nickel might.
Here, it might also be worth considering the shape and the 'coin dropped inside an airplane' scenario mentioned in the reference info. If we think of this in terms of the airplane, just like an observer on an airplane sees a coin drop straight down (as the coin is moving with the airplane), the quarter and nickel on the hill would also be moving with the earth's rotation. However, this effect is negligibly small and not relative to the situation of one rolling and the other not.

that you will blink and not believe it. Fasten your seat belt.
Here are the tools you'll need:
-- Volume of a cylinder = (pi) (radius)² (height)
-- Volume of a sphere = (4/3) (pi) (radius)³
Now ... the question says that your cylinder and your sphere
have the same volume. Fine ! So you can immediately write
an equation saying that their volumes are equal.
(pi) (radius)² (height) = (4/3) (pi) (radius)³
Divide each side by pi: (radius)² (height) = (4/3) (radius)³
Divide each side by (radius)² (height) = (4/3) (radius)
Fill in the given height: (6 cm) = (4/3) (radius)
Multiply each side by 3/4 : (6 cm) x (3/4) = radius
I'm pretty sure that you can take over now and find the radius.
