volume of the right circular cone=1/3pi*r2*h=5 pi*r2*h=15 from the third part of the statement,the radius(r)=1/3r.the height(h)=1/3h the volume of the cone=1/3*pi*(1/3r)2*1/3h =1/3pi*1/9r2*1/3h =1/3*1/9*1/3*pi*r2*h From equation one above pi*r2*h=15
volume=8*5*4 - 7*4*3 =76 CM3
volume=(200+5)*(20+5)*(22.5-2.5) - 200*20*22.5 =38,125 cm3
