So there is a real and imaginary axis
the midopint is just the average of them
average between the reals is (5-3)/2=2/2=1
average between imaginaries is (18i+2i)/2=20i/2=10i

center is 1+10i

Answer:

center of the circle is 1+10i

Step-by-step explanation:

The end points of the diameter are 5 + 18i and -3 + 2i.

We know that the center of the circle is the mid point of the diameter.

Thus, in order to find the center of the circle we find the mid point of the diameter.

The mid point of the diameter with endpoints 5 + 18i and -3 + 2i is given by

\text{Center}=\frac{5-3}{2}+\frac{18i+2i}{2}\\\\\text{Center}=1+10i

Thus, the center of the circle is 1+10i

horrorfan [7]

Answer:

3.8465 *10^7 square kilometers

Step-by-step explanation:

The surface area of a sphere can be found using the formula SA=4\pi r^2. Since the diameter is 3500 km then its radius is half of this. 3500 divided in two is 1,750 units. Substitute r=1,750.

SA=4\pi r^2\\SA = 4 \pi (1750)^2\\SA = 4 \pi *3,062,500\\SA =38,465,000

The surface area of the moon is about 38,465,000 square kilometers. Write this is scientific notation using base. 3.8465 *10^7
