Answer:
A = ![400\pi cm^2](https://tex.z-dn.net/?f=400%5Cpi%20cm%5E2)
Step-by-step explanation:
Area of a circle is:
A = πr²
We are given a radius of 20 cm.
A = πr²
A = π(20)²
A = π400
<em>A = 400πcm²</em>
Hope this helps.
The answer is 72 because 604-72=532 and 532+72=604
The y-intercept is where the line crosses the vertical line on the graph I can't really read the numbers but it looks like 6
I can not see the picture, try adding a better pic
Correlation coefficients whose magnitude are between 0.3 and 0.5 indicate variables which have a low correlation.<span> Correlation coefficients whose magnitude are less than 0.3 have little if any (linear) correlation.</span>
