#11m∠CAR = (1/2)mCR = (1/2)(130°) = 65°#12 and #13m∠ACR = m∠ARC = 1/2(180° - 65°) = (1/2)(115°) = 57.5° #14 and #15mAC = mAR = 2(m∠ACR) = 2(57.5°) = 115°

Mathematics

Cone's volume is $V = \frac{1}{3}Sh$
where S - surface area, h - height
Surface area = $\pi r^2$

r = 18/2=9
h= 14
π = 3.14
$V= \frac{1}{3} \pi r^2h= \frac{1}{3} *3.14*9^2*14= \frac{1}{3} *3.14*81*14=27*14*3.14$ [/tex]
V = 1186.92
