T represents the center of the circle. If you were to measure the 8 1/2 inches all around T, you would end up with a circle whose radius is 8 1/2 (which means its diameter is 2(8 1/2) = 17

Note: a sphere is 3-dimensional (an example would be a ball) so has more than one plane.

Find the area of the sector if m∠ A = π/10 and the circle has a radius of 20 inches.

Leno4ka [110]

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta r^2}{2}\qquad 
\begin{cases}
\theta=\textit{angle in radians}\\
r=radius\\
----------\\
\theta=\frac{\pi }{10}\\
r=20
\end{cases}\implies A=\cfrac{\frac{\pi }{10}\cdot 20^2}{2}$
