Answer:
Option C
Step-by-step explanation:
Given that area of a circle = 452.16 sq metres
Hence radius = 
After rounding off we get radius = 12metres
To find circumference
We know that circumference of a circle = 2pir
= 
Option C is right
Option D is right

Answer:
K=2/5
Step-by-step explanation:
So, I’m assuming that by constant of proportionality you mean slope of the line. To do that, you just figure out how y changes with x. The easiest way to do this is rise over run (y over x). If you look at the graph, there is a point that pass through (0,0) and another that passes through (5,2) so if you count how many spaces we moved up then how many spaces we moved right, you will get the slope of the line. Spaces moved up are 2-0=2 and spaced moved right are 5-0=5. Use rise over run which is going to be 2/5. So, K=2/5.
The formula to convert degrees Fahrenheit to Celsius is:
Convert 59°F to degrees Celsius.
Add the number 59 in the formula, and solve.
Subtract 32 from 59.
Multiply 5 x 9 = 135, then divide 135/9 = 15.
Therefore 59 °F = 15 °C. The correct option is "D".

As you get older your brain develops as you do so when you’re taught math your brain is developing a slightly slower pace than it should be for example if you have a teacher who doesn’t really teach a lot it’s really going to slow down the process of learning
