Question

Find the radius of the base of the cone shown
below.
-29.2 cm-
-22.4 cm

Answer 1

Check the picture below.

`\begin{array}{llll} \textit{using the pythagorean theorem} \\\\ a^2+o^2=c^2\implies a=√(c^2 - o^2) \end{array} \qquad \begin{cases} c=\stackrel{hypotenuse}{29.2}\\ a=\stackrel{adjacent}{r}\\ o=\stackrel{opposite}{22.4} \end{cases} \\\\\\ r=√( 29.2^2 - 22.4^2)\implies r=√( 852.64 - 501.76 ) \\\\\\ r=√( 350.88 )\implies r\approx 18.73~cm`
