Answer:
here is the answer
Step-by-step explanation:
Answer:
314 mi^2 (3 s.f.)
Step-by-step explanation:

diameter of sphere= 10mi
radius of sphere= 10÷2= 5mi
Surface area of sphere= 4(pi)(5^2)= 100pi= 314mi^2 (3 s.f.)
N/(-3) + 5 > 4 /-5
n/(-3) + 5 - 5 > 4 - 5
n/(-3) > -1 / * 3
n/(-3) * 3 > -1 * 3
-n > -3 /*(-1)

4x² - 100 = 0
<u> + 100 + 100</u>
<u> 4x²</u> = <u>100</u>
4 4
x² = 25
x = <u>+</u>5
4(5)² - 100 = 0
4(25) - 100 = 0
100 - 100 = 0
0 = 0
4(-5)² - 100 = 0
4(25) - 100 = 0
100 - 100 = 0
0 = 0
The roots of the equation is positive or negative 5.
