A radius of the base of a right circular cone having carved surface area 528 CM square and slant height 21 CM will be

Question

Lydia · Answer

curved  : surface  : area  : of  : cone  :  =  pi  rl    528 =   frac{22}{7}   times 21  times r    528 = 22  times 3  times r    528 = 66r    r =   frac{528}{66}     r = 8cm    therefore  : radius  : of  : the  : cone  : will  : be  : 8cm
