Answer:
The surface area of the sphere is approximately 4071.5.
Step-by-step explanation:
You can find the surface area of a sphere using this formula: A=4πr^2!
Answer:
C. Clara did not square the radius when solving.
Step-by-step explanation:
She likely solved it like so:
18 x 3.14 = 56.52
56.52 x 4 = 226.08
Through this process, she forgot to square the radius!
Answer:
Tens
Step-by-step explanation:
the three is in the tens value
125 goes to 5^3, 5^2 goes to (3+2) x 5, and 50 stays the same.
So, to be a linear relationship....the difference between the two consecutive "x" values and the difference between the two consecutive "y" values must be same.
In this case,
if we look at the x values , 4 - 3 = 1
3 - 2 = 1
2 - 1 = 1
they are all the same,
<u>BUT,</u><u><em /></u> if we look at the y values, 11.5 - 8.5 = 3
8.5 - 6.5 = 2
6.5 - 4.5 = 2
Here, the differences between the "y" values are all not the same.
<em><u>SO, the relationship is not linear.</u></em>
