Please help me with this

Mathematics
1 answer:
laiz [17]3 years ago
6 0

Answer:

u= 18 square millimeters

Step-by-step explanation:

The surface area formula is A=6a^2

You plug in the given surface area (1944) into A.

Divide both sides of the equation by 6. On the left you will get 324 and on the right you will eliminate 6 and get a^2.

The only way to get rid of an exponent is to square root it, and whatever you do to one side you have to do to the other. The square root of 324 is 18 and that is your answer.

What is the equivalent of pi over 6 radians in degrees?
ra1l [238]

To find the answer to this problem, you can use the unit circle to see that pi over 6 radians is equal to 30°

Another way is to use the equation: degrees = radians • (180 over pi)

In this example, plugging in the radians portion of the equation gives us: degrees = (pi over 6) • (180 over pi), which will become degrees = (180pi over 6pi)

Simplify and pi cancels out to give us degrees = 30

Answer: 30°
