Answer:
The original area would be multiplied by the scale factor of 2² to get the new area.
Step-by-step explanation:
If you double the radius lets so lets do an example
(a=πr²) so
if x is the radius the area would be x²π
double the radius so 2x then the area would be
(2x)²π so 4x²π
4x²π/x²π= 4 so its 4 times greater or
D the last answer or The original area would be multiplied by the scale factor of 2² to get the new area.

Answer:
I'm sorry I cant solve this without an X value but if you tell me the x value i'd be glad to help you out in the comment section below.
Step-by-step explanation:
First we have to find which percent of 2000 numbers are 1360 numbers.
p = 1360 / 2000 * 100 = 68 %
It means that for normal distribution the values 40 and 50 are within +/- 1 standard deviation from the mean ( 45 ).
45 - x = 40 and 45 + x = 50.
x = 45 - 40 = 50 - 45 = 5
Answer:
x = 5
