...Using Pythagorean Theorem (c^2=a^2+b^2) find length of c, which is in this case equal to c=sqrt(8^2+6^2)=sqrt(64+36)=sqrt(100)=10. This means that radius of the circle is r=c/2=10/2=5. So, area of the circle is: A=r^2*pi=5^2*pi=25*pi.

...I was responsible for making sure that school work was always a priority, while making sure that doing homework wasn't the chore that most children know it to be. Personally I am attending college hoping to get a degree in aerospace engineering. I have a lot of experience with math and physics, especially algebra, trigonometry, calculus, and sophomore college-level physics.
