Surface area of a sphere is 4 times pi timers radius^2
aprox pi=3.14
so surface area=145,000,000
145,000,000=4 times 3.14 times rdaius^2
145,000,000=12.56 times radius^2
divide both sdies by 12.56
11544585.987=r^2
square root both sides
3397.73=radius
round to the hundreds
3397 rounded to the hundreds
3400
the answer is D 3,4000 km
Answer:
It's z^11
Step-by-step explanation:
To multiply exponents with the same base (z), you add the exponents so in this case you add 5 and 6 to get z^11
70.24, That should be right

ANSWER
c.
EXPLANATION
The exponential form of complex numbers is given by;
The given complex number in polar form is:
We have r=5 from the question and
We substitute these values to obtain the exponential form:
The correct answer is C
Okay the answer is 3 3/4, 3÷4=.75 then put in the whole number and it is 3.75. 3.75 is bigger than 3.62.. so the answer is 3 3/4
