Answer:
10000π units²
Step-by-step explanation:
From the question given above, the following data were obtained:
Circumference (C) = 100π
Surface Area of sphere (SA) =?
Next, we shall determine the radius. This can be obtained as follow:
Circumference (C) = 100π
Radius (r) =?
C = 2πr
100π = 2πr
Divide both side by 2π
r = 100π / 2π
r = 50 units
Finally, we shall determine the surface area of the sphere. This can be obtained as follow:
Radius (r) = 50 units
Surface Area of sphere (SA) =?
SA = 4πr²
SA = 4 × π × 50²
SA = 4 × π × 2500
SA = 10000π units²
Therefore, the surface area of the sphere is 10000π units²

the 2s mean squared btw
Step-by-step explanation:
1st thing you need to do is to graph the line y = x - 3 as a dashed line, since the it is just a less than symbol. Once the line is graphed, we need to decide which side to shade. I tend to use (0, 0) if at all possible. We check 0 < 0 - 3
Since 0 is not less than -3 then we shade away from the point (0, 0). That is how you find the answer.
Percent increase
find increase
then divided that by original
562157+531285=30872=increase
now put that over original
30872/531285=0.05810817/1
percent means partst out of 100
make bottom number 100
0.05810817/1 times 100/100=5.810817/100=5.810817%
thousanth
5.811%
