Answer:
<em>The surface area of the sphere is 314 mi².</em>
Step-by-step explanation:
According to the given diagram, the diameter of the sphere is 10 mi.
If the radius is 
, then diameter 
So....
<u>Formula for the surface area of a sphere</u>: 
Plugging the value of into this formula, we will get...
![A_{S}=4\pi(5)^2\\ \\ A_{S}=4\pi(25)\\ \\ A_{S}=4(3.14)(25)\ \ [Using\ \pi=3.14]\\ \\ A_{S}=314](https://tex.z-dn.net/?f=A_%7BS%7D%3D4%5Cpi%285%29%5E2%5C%5C%20%5C%5C%20A_%7BS%7D%3D4%5Cpi%2825%29%5C%5C%20%5C%5C%20A_%7BS%7D%3D4%283.14%29%2825%29%5C%20%5C%20%5BUsing%5C%20%5Cpi%3D3.14%5D%5C%5C%20%5C%5C%20A_%7BS%7D%3D314)
So, the surface area of the sphere is 314 mi².
Answer:
Right angle
Step-by-step explanation: you take the 57% angle and ad that with
the 33% angle and you got a prefect 90% also known as a "Right angle"
Answer:
-6
Step-by-step explanation:
y intercept is -6 because formula of gradient is y=mx+c.......c is the y intercept
y = 2x - 3
for x = 0 → y = 2(0) - 3 = -3 → (0, -3)
for x = 2 → y = 2(2) - 3 = 1 → (2, 1)
y = -2x + 5
for x = 0 → y = -2(0) + 5 = 5 → (0, 5)
for x = 2 → y = -2(2) + 5 = 1 → (2, 1)
Answer: A. (2, 1)
