Answer:

A.) 1018 square inches

Step-by-step explanation:

The largest sphere will have a diameter equaling the length of the cube (see picture).

If the side length of the cube is 18 inches, the diameter of the sphere is also 18 inches. Use the surface area formula for a circle:

$SA=4\pi r^2$

For this formula, we need the radius of the sphere. Divide the diameter by 2:

$\frac{18}{2}=9$

The radius is 9 inches. Plug this into the equation:

$SA=4\pi *9^2$

Simplify the equation:

$SA=4\pi *81\\\\SA=324\pi \\\\SA=1017.87$

Round the result to the nearest whole number:

$1017.87$ → $1018$

The surface area is 1,018 inches².

:Done

Picture:

In a 2D version, we can clearly see that if the circle fits snuggly inside of the square, the diameter of a sphere is the same as the length of a side of the cube.

3 in the power of ten word form

Ludmilka [50]

3 in the power of ten means "10^3."

$10^3$

How to solve exponents is to multiply the number as many times as it's exponent. So in this case you will have to multiply ten, three times.

$10\times10\times10=1000$

Which would mean that....

$10^3=1000$

The answer is 10^3.

Hope this helps.

When rolled 4 times, each time has a probability of 1/6
So the problem would be (1/6)^4.
