The circumference is the length of the outer line of the circle. The formula is
-
C = 2πr
C = 2 x 3.14 x 1.5
C = 9.43 km
Explanation:
At the center its weight is zero. Or you can argue by symmetry: if the weight is not zero, in what direction would it act?
Answer: All of these
Explanation: Plates tectonics process is the process that usually takes place near the edges of the planes and it is caused when the earth's outer shell gets divided into various number of plates and get floated over the mantle surface. Faulting occurs when there is any sort of action like extension, compression or transformation in the tectonic plates .
To add fractions with different denominators you must convert the denominators into the lowest common factor. Aka the multiple they all go into. You then times the numerator by what you timsed the denominator by to make sure they both have the same denominator.
Example:
2/5+4/10
They both go into 10.
4/10+4/10= 8/10. 2 became 4 because 5x2=10.
I hope this helped!
You could also simplify 8/10 into 4/5z
