Find the lateral area and volume of the frustum of a right circular cone having a slant height of 14m and the radii of the bases are 4m and 1.5 m respectively.
"A=\\pi(r1+r2)\\times l\\\\ HERE \\,\nr1=4,r2=1.5,l=14\\\\=\\pi(4+1.5)\\times 14\\\\\\pi(5.5)\\times 14\\\\=241.90m^2"
volume
"=\\frac{\\pi H}{3}(\\frac{r1^3-r2^3}{3})\\\\=295.08m^3"
